Question

Bobby is 28 centimeters shorter than Daniel. Roy is 19 centimeters taller than Daniel. Find the difference in height between Roy and Bobby.

Answer 1

I think it is 9 inches. 28-19=9. Don’t rely on this fully. (Just saying)

Answer 2

Let's just say Daniel is 100 centimeters (Doesn't change the answer).

Bobby is 72 centimeters tall (100 - 28), and Roy is 119 (100 + 19) centimeters tall. Subtract: 119 - 72 = 47

You could also do 28 + 19

Answer: 47 centimeters
