Dillon studied 3 6/7 hours for his English test. He studied 5 3/14 hours for his math test. How much longer did he study for his math test? (Simplify the answer and write it as a mixed number.)
3 6/7 = 3 + 6 / 7 = 3 + 2 ∙ 6 / 2 ∙ 7 = 3 + 12 / 14 = 3 12/14
5 3/14 = 5 + 3 / 14 = 4 + 1 + 3 / 14 =
4 + 14 / 14 + 3 / 14 = 4 + 17 / 14 = 4 17/14
5 3/14 - 3 6/7 = 4 17/14 - 3 12/14 =
4 - 3 + 17 / 14 - 12 / 14 = 1 + 5 / 14 = 1 5/14
