Question

carry out the divisions of rational numbers:

i. 2(1/5) ÷ 5(3/6)

ii. (-5/13) ÷ 7/26

iii. 9/11 ÷ (-8)

iv. 5 ÷ 2/5

Answer 1

i. 2(1/5) ÷ 5(3/6)

= 11/5 ÷ 33/6 = 11/5 x 6/33 = 1/5 x 6/3 = 2/5

ii. (-5/13) ÷ 7/26

= (-5)/13 x 26/7 = (-10)/7

iii. 9/11 ÷ (-8)

= (-5)/13 x 26/7 = (-10)/7

iv. 5 ÷ 2/5

= 5/1 x 5/2 = 25/2
