120 gallons/min * 60 minutes/hour = 120*60 gallons/hour

7200 gallons/hour

The easiest way to do this is by using dimensional analyis. That way we cancel out the units.

$\frac{120gal}{1min}\times \frac{60min}{1hr}= 7200$

This rate is 7200 gal/hr

tomas bought a bottle of shampoo that held 10.5 fluid ounces. he uses 1/16 of the shampoo every time he washes his hair. how man

Airida [17]

1) 10.5 = 10 1/2 = 21/2 ounces in bottle

2) 21/2 * 1/16 = 21/32 ounces one use

3) 21/32 * 6 = 63/16 ounces six use

4) 21/2 - 63/16 = 168/16 - 63/16 = 105/16 = 6 9/16 ounces left
