Question

If 30% of a number is 15 what is the number

Answer 1

30/100 = 15/x
30x=1500
30x/30=1500/30
x=50

Answer 2

Another way of saying 30% is 30/100. Since 15 is 30/100 of another number, we can multiply 15 by the reciprocal of 30/100. This gives us:
15 * 100/30
Therefore, The original is 1500/30, or just 50

Answer: 50
