The trail around Mirror Lake in Yosemite National Park is 5 miles long.
The tables below show the fraction of miles each hiked:
Hiker Fraction of miles hiked
Andrea 2/5
Jon 1/2
Callie 4/5
9. What fraction describes how much more of the trail Jon hiked than Andrea hiked?
10. What fraction describes how much more of the trail Callie hiked than Jon hiked?
Answer:
9. 1/10
10. 3/10
Step-by-step explanation:
9. What fraction describes how much more of the trail Jon hiked than Andrea hiked?
This is calculated as the number of miles Jon hiked - The number of miles Andrea hiked
1/2 - 2/5
= The Lowest Common Denominator is 10
= [(5 × 1) - (2 × 2)] /10
= [5 - 4] /10
= 1/10
The fraction that describes how much more of the trail Jon hiked than Andrea hiked is 1/10
10. What fraction describes how much more of the trail Callie hiked than Jon hiked?
This is calculated as the number of miles Callie hiked - The number of miles Jon hiked
4/5 - 1/2
= The Lowest Common Denominator is 10
= [(4 × 2) - (1 × 5)] /10
= [8 - 5] /10
= 3/10
The fraction describes how much more of the trail Callie hiked than Jon hiked is 3/10
