Problems with Ratios

A car moving at a constant speed travels 130 miles in 2 hours

Write a ratio of distance to time and use it to find how far the car will travel in 5 hours.

Distance : Time

130 miles : 2 hrs -> \frac{130 miles}{2 hrs} \cdot \frac{5 hrs}{1} = 325 miles in 5 hrs


Sam made 8 out of 24 free throws. Use a proportion to show how many free throws Sam would make out of 60 attempts.

\frac{8 made}{24 attempts} \cdot \frac{60 attempts}{1} make 20 out of 60 attempts
