Answer 1

To find the unit rate, divide the time it takes to mow a portion of the lawn by the portion that is being mowed.

The unit rate would be:
12 hours / 23 of the lawn

Simplifying, we get:
12/23 hours per portion of the lawn

Therefore, the unit rate is approximately 0.52 hours per portion of the lawn.

To find how long it will take to mow the entire lawn, multiply the unit rate by the total number of portions of the lawn:
0.52 hours per portion of the lawn * 1 portion (the entire lawn) = 0.52 hours

So, it will take approximately 0.52 hours to mow the entire lawn.
