Question

The janitor at a school discovered a leak in a pipe. The janitor found that it was leaking at a rate of 11 fl oz per hour. How fast was the pipe leaking in gallons per day? Round to the nearest tenth

Answer 1

Here's what you need to know in order to answer this:

1 gallon = 128 fl oz
and
1 day = 24 hours.

Use those facts to invent fractions equal to ' 1 '.
Then use those to change the units of the "11 fl oz per hour".
You can multiply them ... since their value is ' 1 ', they won't
change the value of the "11 fl oz per hour", only the units.

(11 fl oz/hr) x (24 hr/da) x (1 gal / 128 fl oz)

= (11 x 24 x 1 / 128) (fl-oz - hr - gal) / (hr - da - fl-oz)

= 2.0625 gal/da
