# What Is 18/30 Reduced To (2023)

Mathematics Middle School

18/30, is reduced to 9/15 then 3/5.

9/15 first, because 18 and 30 are both divisible by 2.

18÷2=9 and 30÷2=15.

Then how I got 3/5, was because both 9 and 15 are divisible by 3.

9÷3=3 and 15÷3=5 so the final answer that you are looking for, is 3/5.

Step-by-step explanation: In order to write the fraction 18/30 in lowest terms, we divide the numerator and the denominator by the greatest common factor of 18 and 30 which is 6.18 divided by 6 is 3 and 30 divided by 6 is 5 so 18/30 written in lowest terms is 3/5.

What is 48/56 in simplest form

6/7 because 48 divided by 8 is 6 and 56 divided by 8 is 7

48/56 can be simplified by dividing 48 by 8 and you get 6. Then, you divide 56 by 8 equals 7. So, 48/56 in simplest form is 6/7.

A \$40 jacket is on sale for 30% off what is the sale price

So 40=100%
find 100%-30%=70%
70% of 40
'of' can be translated to multiply
70% times 40
percent means parts out of 100 so
70%=70/100=7/10=0.7
so
.7 times 40=28
the sale price=\$28

Directions: Drag each tile to the correct box. Order the following conditions in order from the largest number of possible triangles to the least number of possible triangles.

Condition A: a perimeter of 12 and even-numbered side lengths
Condition B: a side length of 4 inches, a side length of 5 inches, an included angle of 110º, and a perimeter of 11 inches
Condition C: a right triangle with an area less than 13 square inches and odd-numbered leg lengths greater than 1 inch
Condition D: an isosceles triangle with two angles that measure 50º

D, C, A nad then B
Figure out the number of possible triangles that fitcondition A. There are 3 possible combinations of three even numbers that sum to 12.Of these three, there is only one where every length is less than the sum of the other two:4 inches,4 inches,4 inches.So, there is only one triangle that fitscondition A.Figure out the number of possible triangles that fitcondition B. Since the perimeter and two side lengths are given, subtract the two side lengths from the perimeter to get the length of the third side.Sketch a triangle with lengths of2 inches,4 inches,and5 inches.From the sketch, the angle between the4-inchlength and5-inchlength has to be the smallest angle. Since it has to be the smallest angle, it cannot be more than a right angle. So, there is zero triangles that fitcondition B.Figure out the number of possible triangles that fitcondition C. For the area to be less than13 square inches, the product of the legs must be less than26 square inches. The right triangles withodd-numberedlegs greater than1 inchwhose product is less than26 square inchesare shown below.So, three triangles fitcondition C.Figure out the number of possible triangles that fitcondition D. If two angles of an isosceles triangle measure 50º, the third can be found by subtraction both angle measures from 180º.So, the angle measures must be 50º, 50º, and 80º. There is no condition on the lengths, so there are an infinite number of triangles that fitcondition D.Therefore, the conditions in order of greatest possible triangles to least are shown below.condition D,condition C,condition A,condition B

A red string of lights blinks once every 3 seconds while a string of blue lights blink once every 4 seconds. How many times will both sets of lights blink at the same time in 60 seconds?

The string of red lights will blink 20 times and the blue lights will be 15 60 divided by 4 is 15 and 60 divided by 3 is 20

Vicki puts 10 books on a shelf.The 10 books take up 28 centimeters.What is the mean (average) thickness of her books?= 2.8 cmThe shelf is 120 centimeters long.Vicki fills the shelf with a mixture of books like the first ten books.Estimate how many books she can get on the 120 cm shelf.Please show your working out.

So each book is an average of 2.8 cm
so 120 divided by each book=number of books
120/2.8=42.85
round down since you can't fit .85 of a book on a shelf

Explain how you can use a number line to show that 5/8 is greater than 3/8

You can start by drawing a number line and labeling it with eighths. ( 1/8, 2/8, etc.) Then you can place a dot on 3/8 and 5/8. From there, it's clear to seethat 5/8 is greater than 3/8.

Draw a fraction number line and put a dot where each fraction from greatest to least is. Hope this helps

What is 3/4 divided by 1/24

Dividing fractions is the same thing as multiplying by the reciprocal

3/4 x 24/1 = 18

3/4 divided by 1/24, must do the reciprocal (flip) of 1/24 which is 24/1, when do this you now multiply, 3/4x24/1=72/4=18

What is 151/24 simplified

Well 151 divided by 24 is 6 remainder 7 so the mixed number would be 6 and 7/24

Every prime number greater than 10 has a digit in the ones place that is included in which set of numbers below?

The numbers are all prime and odd numbers
11, 13,17,19,23,29,31,37,
so the numbers are 1,3,7,9
because
2 is even and if it ends in 2 then divisible by 2
this crosses out all the even numbers :2,4,6,8
if it ends with 5 then it is divisible by 5 cross 5 out
so the numbers are 1,3,7,9
if the number ends with these number that doesn't mean that it is always prime exg 21 is not prime, 49 is not prime
so the numbers 1,3,7,9

N^2+16n+60 over 36-n^2

Factor
36-n^2 is difference of 2 perfect squares
a^2-b^2=(a-b)(a+b)
6^2-n^2=(6-n)(6+n)
factor

n^2+16n+60
find what 2 numbers multiply to 60 and add to 16
factors of 60=2,2,3,5
the numbers are 10 and 6
so factored out
(x+6)(x+10)
(x+6)=(6+x)

so the equation is
[(x+6)(x+10)]/[(6+x)(6-x)]=[(6+x)/(6+x)] times (x+10)/((6-x)=1 times (x+10)/(6-x)

Using the order of operations rule, solve the following: 12 ÷ 2 + 4 – 2 × 3 = ? A. 24 B. 36 C. 0 D. 4

The answer is D, because you have to divide 12 by 2 so you get 6 then 2 times 3 to get 6, so now you should have 6+4-6 which will then become 10-6 which equals 4

Which one of the following groups of numbers includes all prime numbers? A. 7, 17, 63, 67 B. 3, 11, 23, 31 C. 1, 3, 11, 23 D. 2, 3, 5, 15

The prime number is a natural number greater than 1 that has no positive divisors other than 1 and itself.

A.
7 - is a prime number
17 - is a prime number
63 - is not a prime number because 63 = 3 × 21

B.
3 - is a prime number
11 - is a prime number
23 - is a prime number
31 - is a prime number

C.
1 - is not a prime number

D.
2 - is a prime number
3 - is a prime number
5 - is a prime number
15 - is not a prime number because 15 = 3 × 5
