Gnesinka [82]

Answer:

There are 20 kids total in the class.

Step-by-step explanation:

15/100 × 20 = 3  

You can use direct proportion for any percent calculation.

Compare each number with its percent.

3 i s  15 %  of what number? Let the number be  x

So, 3  represents  15 %  and  x  represents  100 %

x/ 100   =  3/15  

Multiply by  100  to isolate  x

x  = \frac{3 x 100}{15}

x  =  20

Check:  15/ 100 × 20 = 3
