One brick is one kilogram and half a brick heavy. What is the weight of one brick? (This is an easy, yet cool math game for kids and adults.)

Answers (1)

Let the weight of brick = x kg
Given that one brick is 1 kg and half a brick heavy. Thus

x=1+ \frac{x}{2} \\ \\ \Rightarrow x- \frac{x}{2} =1\\ \\ \Rightarrow \frac{x}{2}=1\\ \\ \Rightarrow x=2*1= \boxed{2\ kg}
