Question

(6 1/4-41/8)*4+3 1/3: 2 1/2=

Answer 1

         1          2   4         3
(6 1/4 - 4 1/8) * 4 + 3 1/3 : 2 1/2 = 9 5/6
1) 6 1/4 - 4 1/8 = 6 2/8 - 4 1/8 = 2 1/8
2) 2 1/8 * 4 = 17/8 * 4 = 17/2 = 8 1/2
3) 3 1/3 : 2 1/2 = 10/3 : 5/2 = 10/3 * 2/5 = 2/3 * 2 = 4/3 = 1 1/3
4) 8 1/2 + 1 1/3 = 8 3/6 + 1 2/6 = 9 5/6
