Answer:

6 : 5

Step-by-step explanation:

Rate = \frac{6}{5}

But Rate is also equal to number of lawns mowed in a certain amount of time.

Since ratio should always be in terms of simple whole numbers.

If 6/5 lawns are mowed in 1 hour, then,

6 lawns will be mowed in:

=\frac{6 \times 1}{\frac{6}{5} }

= 5 hours.

therefore, 6 laws will be mowed in 5 hours.

Ratio of lawns to hours in 6:5
