Question

Sara's teacher has 6 7/8 cups of water. She used 4/8 a cup of water to water the plant on her desk and 3 2/8 cups for some students who were thirsty. How much water does she have left over?

Answer 1

Amount of water left = 25 / 8 cups

Explanation:

Given:

Amount of water teacher Sara have =
`6(7)/(8)` cups = 55 / 8 cups

Amount of water teacher used = 4/8 cups

Amount of water used by student =
`3(2)/(8)` cups = 26 / 8 cups

Find:

Amount of water left

Computation:

Amount of water left = Amount of water teacher Sara have - [Amount of water teacher used + Amount of water used by student]

Amount of water left = [55/8] - [4/8 + 26/8]

Amount of water left = [55/8] - [30/8]

Amount of water left = [55-30] / 8

Amount of water left = 25 / 8 cups
