Question

1)3 1/8:((3 13/24-4 5/12)*4/7+(2 7/12-3 1/18)*1 10/17=
Помогите пожалуйста.

Answer 1

3 1/8 : ((4 5/12 - 3 13/24) * 4/7 + (3 1/18 - 2 7/12) * 1 10/17) = 2 1/2
1) 4 5/12 - 3 13/24 = 4 10/24 - 3 13/24 = 3 34/24 - 3 13/24 = 21/24 = 7/8
2) 7/8 * 4/7 = 4/8 = 1/2
3) 3 1/18 - 2 7/12 = 3 2/36 - 2 21/36 = 2 38/36 - 2 21/36 = 17/36
4) 17/36 * 1 10/17 = 17/36 * 27/17 = 27/36 = 3/4
5) 1/2 + 3/4 = 2/4 + 3/4 = 5/4 = 1 1/4
6) 3 1/8 : 1 1/4 = 25/8 : 5/4 = 25/8 * 4/5 = 5/2 = 2 1/2
