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

Answer:

Amount of water left = 25 / 8 cups

Step-by-step explanation:

Given:

Amount of water teacher Sara have = $6\frac{7}{8}$ cups = 55 / 8 cups

Amount of water teacher used = 4/8 cups

Amount of water used by student = $3\frac{2}{8}$ 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
