Question

A book sold 33,200 copies in its first month. Suppose this represents 7.4% of the number of copies sold to date. How many copies have been sold to date?

Answer 1

448,648

Explanation:

33,200/.074 = 448,648

Answer 2

Answer: 448648

Explanation:

33,200 copies represent 7.4% of the total amount

-----------------------------------------------------

#1 33,200 ÷ 7.4%

- this is because how we get 33,200 by calculation is use the total amount and times 7.4% to get 33,200. So we are just working backwards. Since it was times before, then we divide after.

33,200÷7.4%

=33,200÷0.074

≈448648 (you can't round up when the real amount is less the exact amount)
