Answer (3)

To divide fractions, multiply the dividend by the reciprocal of the divisor.
12 ∗ 4 5 ​ = 4 60 ​ = 15
4 3 ​ ∗ 7 8 ​ = 28 24 ​ = 7 6 ​
8 ∗ 6 7 ​ = 6 56 ​ = 3 28 ​
11 8 ​ ∗ 4 7 ​ = 44 56 ​ = 11 14 ​
4 ∗ 5 7 ​ = 5 28 ​
4 3 ​ ∗ 1 12 ​ = 4 36 ​ = 9

(12)÷(4/5)=12*(5/4)=60/4=15
(3/4)÷(7/8)=3/4*8/7=24/28=12/14=6/7
(8)÷(6/7)=8*(7/6)=56/6=28/3
(8/11)÷(4/7)=8/11*7/4=56/44=14/11
(4)÷(5/7)=4*(7/5)=28/5
(3/4)÷(1/12)=3/4*12/1=36/4=9
