How many children are working around the world today, according to the ILO?

a. 215,000

b. 2.15 million

c. 21.5 million

d. 215 million

b. 2.15 million

In this problem it states that one tenth or only 10% is Canada’s population to the United States. Hence with the steps we can identify the population of the United States.

1. 10 % = 32 million or 0.1 = 32 million

2. Then 32 million / 0.1 = 320, 000, 000 million

Therefore there are 320, 000, 000 million living in the United States

Adding one zero. Why the zeroes? It is the result because of the power of 10 in a hundred percent population coming from the Canada’s population. Take note that 100% = 320, 000, 000 million of the USA while 10% of it is Canada so we divide it by 0.1 which is 32, 000, 000 (the power of ten)
