Moses and Louis ran laps after school to train for the basketball team. The ratio of the number of laps Moses ran to the number of laps Louis ran was two to three. If Moses ran 8 laps, how many laps did Louis run?

Louis ran 12 laps when Moses ran 8

Step-by-step explanation:

Given

Represent Moses with M and Louis with L

Required

Determine L when M = 8

Represent as a fraction

---- (1)

Represent the required as a ratio;

Convert to fraction

------ (2)

Equate (1) and (2)

Multiply both sides by L

Multiply both sides by

Hence Louis ran 12 laps when Moses ran 8

is means division by fractions

step-by-step explanation:

b. 1.25 hr

step-by-step explanation:

if you have a constant speed of 60 mph, then you have a ratio between 60 mi. to 1 hr. dividing both sides by 60 we get the ratio

1 mi. to

then mult. both sides by 75 we get the ratio

75 mi. to

simplifying we get

75 mi. to

or 1.25 hr.
