Question

A landscaper had 5 tons of rock to build decorative walls. He used 1/4 ton of rock for each wall. How many decorative walls did he build?

Answer 1

He can build four walls if he uses 1 tonne. therefore he can build 4 x 5 = 20 walls with 5 tonnes

Answer 2

20 walls because if each wall needs 1/4 times the denominator by the amount he has and that gives you the answer
