A group of people are going on a 5 mil hike. They walked 2 1/10 miles in the morning and 1 1/4 mils during the first hr of the afternoon. How many miles do they have to walk?

Answer 1

Answer: 1 13/20 miles

Explanation:

$5 - 2\cfrac{1}{10} - 1 \cfrac{1}{4} = 5 \cfrac{0}{20} - 2\cfrac{2}{20} - 1 \cfrac{5}{20} = 4 \cfrac{20}{20} - 2\cfrac{2}{20} - 1 \cfrac{5}{20} = 1 \cfrac{13}{20}$
