If the shapes are similar, the correspondent sides are in proportion:

Let's plug the values and solve for x:

Multiply both sides by x to get

The only feasible solution, though, is
, because it wouldn't make sense to have negative lengths.
Answer: 50%
Explanation:
A child is either a boy or a girl
P(a boy) = 1/2 = 50%
Dear Sadaadams73, to solve this problem, we use the formula I=Prt. The equation will look like 400=8000 x 0.02 x <em>t. </em>Multiply 8000 by 0.2 to get 1600t=400. Then divide both sides by 400 to get 4 years.
1/2 because it is a fraction
