Question

Apple decided to walk $9\frac{3}{10}$mi from his house to the beach. In the first hour, he walked $3\frac{4}{5}$mi. In the second hour he walked $2\frac{9}{10}$mi. How much farther did he have to go?

Please show your work!

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
