Question

The diagram was 3 inches wide and 5 inches high. How wide would the diagram be if it were 6 inches high?

Answer 1

3 3/5 inches

Explanation:

Write and solve an equation of ratios:

x 6 in

-------- = --------

3 in 5 in

Then 5x = 3(6), or 5x = 18, or x = 18/5.

The diagram would be 18/5 inches wide, or 3 3/5 inches wide.
