To find the percent change of something you need to set up a proportion.

amount change (original - new) over new number

x over 100

then cross multiply. Example

25 x
----- ------
50 100

25 x 100 = 2500
2500/50 = 50

So the answer is 50%

The first problem’s answer is true. (P.S. If you don’t understand this type of problems then plug in variables for them. It helps check your answer and solve them too.)

The second problem’s answer is false.

First of all, I plugged in for the variable a to be 6 for the first problem. Second, I plugged in numbers for the variables and x was 5 and x was 2 for the second problem. You can check the steps in the image I took. (P.S. You can use the MathPapa calculator online to solve these problems and plug in the variables.)

(I couldn’t upload the second problem’s step by step sorry, but if you need it then just use the MathPapa calculator by plugging in numbers for the variables.)
