Trevor takes 5/6 of a minute to run one lap around the track. If Trevor runs around the track at the same pace for 1/4 hour, how many laps will Trevor run?
Trevor will run 18 laps.
If 1 lap is equal to 5/6 of a minute that is also 50 seconds.
Additionally, 1/4 hour is equal to 15 minutes.
To find the answer, you divide the total time (15 minutes) by the time it takes to run one lap 5/6 of a minute.
15 divided by 5/6 = 15/1 divided by 5/6 =
15/1 x 6/5 can be cross-reduced to 3/1 x 6/1 = 18/1 or 18 laps.

Luke spends .4 of his monthly income on rent, .2 of his monthly income on utilities, and .75 of the remaining amount on food and recreation. Luke saves the rest. If the amount he saves each month is $193.50, what is Luke's monthly income?
You can't use a calculator on the test, so don't use one when you are practicing these problems. Show all of your work.
Luke's monthly income is $1,935.00
.4 = 40% (rent)
.2 = 20% (utilities)
.75 of 40% = .3 or 30% (food and recreation)
The total for these three categories is 90%.
That leaves 10% of his salary left. 10% is $193.50
$193.50 divided by 10 = $19.35; which is 1%.
To find 100%, you take 1% ($1.35) and multiply by 100%. 100 x 19.35 = $1,935.00
