Question

Apple decided to walk
`9(3)/(10)`mi from his house to the beach. In the first hour, he walked
`3(4)/(5)`mi. In the second hour he walked
`2(9)/(10)`mi. How much farther did he have to go?

Answer 1

2 3/5

first convert each fractions into improper fractions.
9 3/10 = 93/10
3 4/5 = 19/5
2 9/10 = 29/10

then, add how much he walked in both hours together,

19/5 + 29/10 = 67/10

next, subtract your sum from the total amount Apple has to walk,

93/10 - 67/10 = 13/5

lastly, convert back to mixed number,
2 3/5
