Question

0.3% of what number is $0.66?

Answer 1

Hi there! The answer is $220

If 0.3% of a certain number equals $0.66,
then 0.1% of that number equals 0.66 / 3 = $ 0.22.

If we want to know the original number we must multiply by 1000 (since 0.1% * 1000 = 100%). We get the following:
0.22 * 1000 = $220

Therefore, 0.3% of $220 is $0.66

Answer 2

$0.66 / 0.3% = 2.2
Check:
2.2 * 0.3 = 0.66

Hope this helps!
