in a recent year the world production of wheat was about 5.2x10^8 metric tons. Canada produced 1/25 of this wheat. About how much wheat did Canada produce?

Question

A.) 20.8 x 10^8
B.) 2.08 x 10^7
C.)2.08 x 10^6
D.)20.8 x 10^7

Answer 1

1/25 = 0.04 = 4x10^-2
5.2x10^8 * 4x10^-2 = (5.2*4)x10^(8-2) = 20.8 x 10^6 = 2.08 x 10^7
