Complete the sentence to explain how to use mental math to express 12/25 as a percent
Vlada [557]

Answer: It's 48%. See below.

Step-by-step explanation:

By definition, percent means out of a hundred. For instance, 10 percent is 10 out of 100.

One way to make \frac{12}{25} a percent is by making the denominator 100. In order to do so, multiply the numerator and the denominator by 4, since 25 times 4 is 100.

\frac{12}{25}  =  \frac{48}{100} = 48 %

This is very simple, and mental math is definitely possible. Hope this help.

If 6 is added to three quarters of a certain number, the result is 42 . Find the original number​
Basile [38]

Answer:

Step-by-step explanation

Hello!

3x/4 + 6=42

3x/4=42-6 = 36

3x = 36*4

3x = 144

x= 144/3 =48

3/4 of  48  = (48*3)  / 4 =36

36+6=42

the original number​ is 48

Can somebody answer and explain?<br> ( brainliest )
svlad2 [7]
A: 6/8, 9/12, 12/16
b: 6/14, 9/21, 12/28
c: 6/9, 2/3, 4/6
d: 1/4, 2/8, 2/12

In order to find equivalent fractions for a fraction is multiply or divide the numerator and denominator by the same number.

For example, 3/4=6/8 because 3x2=6 and 4x2=8, 6/8.

Hope this helps!
