Terri can swim 3 laps in 2.5 minutes. To find how long it takes to swim 20 laps, you can make a proportion.

\frac{Lap}{Time}

Put the amount of laps on the top and the time(minutes) at the bottom.

\frac{3}{2.5} = \frac{20}{x}

Cross multiply:

20 \times 2.5 = 50

Divide by 3:

50 \div 3 = 16 \frac{2}{3} \rightarrow 16.67

It would take Terri 16 \frac{2}{3} OR 16.67 minutes to run 20 laps.

Sedaia [141]

The total ratio is 5

The number of comedy movies watched is 12

The number of other movies watched is 18

<h3>What is a ratio?</h3>

Ratio is a comparison of two or more numbers that indicates their sizes in relation to each other. Therefore,

He has watched 2 comedy movies for every 3 other movies. The total movies he has watched is 30. Therefore,

  • 2:3

Ratio of comedy to total movies is as follows:

  • 2 : 5

number of comedy movies watched = 2 / 5 × 30 = 60 / 5 = 12

number of other movies watched = 3 / 5 × 30 = 90 / 5 = 18

Therefore,

total ratio = 5

number of comedy movies watched = 12

number of other movies watched = 18
