0.5% of a is 3 then what is a?

Step-by-step explanation:

0.5%a  =  3

    ×10    ×10

 5%a    =  30

   ×20     ×20

100%a  = 600

   a = 600

well there are two answers for that.

1: you need 120 ones then that will equal up to 120.

2: you could also do one 100 and 2 tens.

those are the answers that i have thought of.

a is the correct
