Question

(2(целых)1/6+3(целых)1/4):2(целых)3/5+2/3*2(целых)1/4-1/6

Answer 1

(2 1/6 + 3 1/4) : 2 3/5 + 2/3 * 2 1/4 - 1/6 = 3 5/12
1) 2 1/6 + 3 1/4 = 2 2/12 + 3 3/12 = 5 5/12
2) 5 5/12 : 2 3/5 = 65/12 : 13/5 = 65/12 * 5/13 = 25/12 = 2 1/12
3) 2/3 * 2 1/4 = 2/3 * 9/4 = 3/2 = 1 1/2
4) 2 1/12 + 1 1/2 = 2 1/12 + 1 6/12 = 3 7/12
5) 3 7/12 - 1/6 = 3 7/12 - 2/12 = 3 5/12
