If 10 percent of a number equals 30, find 40 percent of that number.

The answer is 120
To find the whole number given the fraction and the number by the fraction, you multiply the number by the reciprocal/inverse of the fraction.
30 * 100/10= 300
So the whole number is 300 and to find 40% just multiply
300 * 40/100 = 120
