Question

Помогите пожалуйста решить Срочно!!!! 3 1/3:2/3*1/5; 4/5*2 1/2:6; 3 1/5*5/8:2/7; 26:3 1/4*1/16; 4 1/8*6/11:2 1/4; 1 1/7*3/4:3/10

Answer 1

3 1/3 ÷ 2/3 = 10/3 × 3/2 = 5/1 × 1/5 = 1
4/5 × 2 1/2 = 4/5 × 5/2 = 2/1 × 1/6 = 1/3
3 1/5 × 5/8 = 16/5 × 5/8 = 2/1 × 7/2 = 7
26/1 ÷ 3 1/4 = 26/1 × 4/13 = 8/1 × 1/16 = 1/2
4 1/8 × 6/11 = 33/8 × 6/11 = 3/4 ÷ 2 1/4 = 3/4 × 4/9 = 1/3
11/7 × 3/4 = 33/28 ÷ 3/10 = 33/28 × 10/3 = 55/14 = 3 13/14
