Question

The sum of the heights of a giraffe and a baby giraffe is 15m. If the baby giraffe has a height which is 2/3 that of the giraffe, what is the height of the baby giraffe?

Answer 1

mama giraffe: x

baby giraffe: $\frac{2}{3} x$

$x + \frac{2}{3}x$ = 15

$(3)x + (3)\frac{2}{3}x$ = (3)15

3x + 2x = 45

5x = 45

x = 9

baby giraffe: $\frac{2}{3} x$ = $\frac{2}{3}(9)$ = 2(3) = 6
