To find out how many hours Gavin spent mowing the grass, you can use the percentage given (30%) and the total hours he spent on outdoor chores (45 hours).
Here's how to calculate it:
-
Convert the percentage into a decimal: 30% = 30/100 = 0.30
-
Multiply the total hours by the decimal: Hours spent mowing the grass = 45 hours × 0.30 = 13.5 hours
So, Gavin spent 13.5 hours mowing the grass.
