Zachary and Erin went to a climbing centre.

Question

Zachary climbed 6/7 of the way up an 11.1m high wall. Erin climbed 4/9 of the way up a 19.7m high wall.
What is the difference between the heights that Zachary and Erin climbed?
Give your answer to 2 decimal places.

Answer 1

Zachary climbed: 6/7 * 11.1m = 9.51m
Erin climbed: 4/9 * 19.7m = 8.76m

The difference between their heights climbed is:

9.51m - 8.76m = 0.75m

Therefore, the difference between the heights that Zachary and Erin climbed is 0.75m.
