Question

express the first quantity as a percent of the second quantity

Answer 1

Assume the 1st quantity is 120, and the 2nd quantity is 240. So first, we have to form a fraction with them = 120/240. Then we multiply the fraction with 100 = 120/240 x 100= 50. This means that 120 is 50% of 240. Let us try another one. Assume the 1st quantity is 73, and the second quantity is 365. We form a fraction = 73/365. We multiply it by 100 = 73/365 x 100= 20%. Hence, 73 is 20% of 365. Now, one more... Assume the 1st quantity to be 500, and the 2nd quantity to be 10,000. So let us form a fraction = 500/10000. We multiply by 100 = 500/10000 x 100 = 5. Thus, 500 is 5% of 10,000.

Answer 2

Divide the first quantity by the second quantity and multiply 100 to the result.
For example, if a is the first quantity and b is the second quantity,
First quantity as a percent of the second quantity = (a/b)*100
