First find the estimate of the quotient then find the exact quotient 3 3/7 divide by 1 4/9

Estimate of the quotient:

3 3/7 = 3+0.428571=3.428571

1 4/9 = 1+0.444444=1.444444

(3 3/7) / (1 4/9) = 3.428571 / 1.444444 = 2.373627

Estimate of the quotient: 2.373627

Exact quotient:

3 3/7 = (7*3+3) / 7 = (21+3) / 7=24/7

1 4/9 = (9*1+4) / 9 = (9+4) / 9=13/9

(3 3/7) / (1 4/9) = (24/7) / (13/9) = (24/7) * (9/13) = (24*9) / (7*13) = 216/91

Exact quotient: 216 / 91 = (182+34) / 91 = 182 / 91 + 34 / 91 = 2 34/91

Exact quotient: 216/91 = 2 34/91

The answer is 4/7 i hope this work
