Answer:

A) H+4

Step-by-step explanation:

I do this in a different way, but i'll do it in both

Mine:

30 ÷ 2 = 15

125% of what number is 25
Mazyrski [523]
We can create a equation to find out.

since we are finding a number where when multiplied by 1.25(this is the decimal form of the percentage) gives us 25, we know that the number we are finding is less than 25. here is the equation.

1.25(x)=25

divide both sides by 1.25 to get "x" alone.

x= 20
