((1 1/2 +2 2/3 +3 3/4) )/(14-15 1/8:2 1/5)

Question

((1 1/2 +2 2/3 +3 3/4) )/(14-15 1/8:2 1/5)

Answer 1

((1 1/2 +2 2/3 +3 3/4) )/(14-15 1/8:2 1/5) = (1 6/12 +2 8/12 +3 9/12)/(14 - 121/8 ÷ 11/5) = (6 + 23/12)/(14 - 121/8 × 5/11) = (7 11/12)/(14 - 55/8) = (7 11/12)/(14 - 6 7/8) = (7 11/12)/(7 1/8) = 95/12 ÷ 57/8 = 95/12 × 8/57 = 10/9 = 1 целая 1/9

Answer 2

1)1 1/2+2 2/3+3 3/4=1 6/12+2 8/12+3 9/12=6 23/12=7 11/12
2)15 1/8:2 1/5=121/8*5/11=55/8=6 7/8
3)14-6 7/8=7 1/8
4)7 11/12:7 1/8=95/12*8/57=(5*2)/(3*3)=10/9=1 1/9
