Isaiah will mow 9 lawns in 3 hours at the given rate.

Step-by-step explanation:

Given,

Lawns mowed in 25 hours = 75 lawns

We will find unit rate in terms of lawns;

75 lawns = 25 hours

1 lawn = $\frac{25}{75}=\frac{1}{3}\ hour$

9 lawns = $\frac{1}{3}*9$

9 lawns = 3 hours

Isaiah will mow 9 lawns in 3 hours at the given rate.
