BSEP Ratios and Proportions 4

Question 1

A runner completes 5 laps in 8 minutes. At this rate, how many laps can she complete in 24 minutes?

Accepted Answer

15 laps

Answer

5/8 = x/24, so x = (5 × 24) / 8 = 15 laps.

Question 2

A recipe makes 48 cookies using 3 cups of sugar. How many cups of sugar are needed to make 80 cookies?

Accepted Answer

5 cups

Answer

3/48 = x/80 gives x = (3 × 80) / 48 = 5 cups.

Question 3

A gear with 24 teeth turns 3 times for every 2 turns of a gear with 36 teeth. If the larger gear turns 10 times, how many times does the smaller gear turn?

Accepted Answer

15 times

Answer

The ratio is 3:2, so 3/2 = x/10 gives x = 15 turns.

Question 4

On a scale drawing, 2 cm represents 5 meters. If a wall is 17.5 meters long, how long is it on the drawing?

Accepted Answer

7 cm

Answer

2/5 = x/17.5 gives x = (2 × 17.5) / 5 = 7 cm.
