12.5% of a number is 25, find the number
tankabanditka [31]

Answer:

200

Step-by-step explanation:

Let's call the number x :
12.5% of x = 25

Changing 12.5% into decimal would be 0.125

Now we have the equation :

0.125x = 25

Divide both sides by 0.125 to make x the subject :

x = 25 ÷ 0.125

x = 200

To check we can substitute this value into the question :

12.5% of 200 = 25

Hope this helped and have a good day

1,3,5,7,9,11,13,15,17,19,21,23,25,27,29,31,33,35,37,39

31+33+35+37+39 = 175
Add the totals:
25+75+125+175
The answer would be 400.
