7 is what percent of 0.03?

Answer 1

30% of what number is 7?

Answer 2

Well, 100% of something is "all of it". So 100% of 6 is 1 * 6.

50% of something is half of it. So 50% of 6 is .5 * 6.

25% of something is one quarter of it, so 25% of 6 is 1/4 * 6 = 0.25 * 6.

Notice a pattern?

Answer 3

30% of what number is 7?

30% of x = 7
30/100 * x = 7
0.3x = 7

Answer 4

30% of some number x is 0.3 * x.
