Further explanation
<u>Given:</u>
A community bike ride offers a short 5.7-mile ride for children and families.
The short ride is followed by a long ride, 5²/₃ times as long as the short ride, for adults.
A woman bikes the short ride with her children, and then the long ride with friends.
<u>Question:</u>
How many miles does she ride together?
<u>The Process:</u>
Let us make a pattern for the short ride:
Let us do a multiplication on a fraction at first.
We crossed out 3 and 57.
Then we make a pattern for the long ride, 5²/₃ (five and two third) times as long as the short ride:
A woman bikes the short ride with her children, and then the long ride with friends. Let's calculate how many miles does she ride together.
- The short ride:
- The long ride:
Thus, she rides 38 miles together.
