On Monday, 5/8 inch of rain fell in 2/3 hour.
Which value representa the unit rate, in inches per hours?
5/12
15/16
16/15
31/24
To find the unit rate in inches per hour, we need to divide the amount of rain (5/8 inch) by the time it took for that amount to fall (2/3 hour).
So, the unit rate is (5/8 inch) ÷ (2/3 hour).
To divide by a fraction, we multiply by the reciprocal of the fraction.
So, (5/8 inch) ÷ (2/3 hour) = (5/8 inch) × (3/2 hour).
Next, we can simplify the multiplication:
(5/8) × (3/2) = (15/16) inch.
Therefore, the unit rate in inches per hour is 15/16.
The value that represents the unit rate, in inches per hour, is 15/16.
