Question

Solve :

i. 5/12 + 7/16

ii. 3(2/5) - 2(1/4)

iii. 12 x (-10)/3

iv 4(3/8) ÷ 25/18

Answer 1

i. 5/12 + 7/16

20/48 + 21/48

= (20 + 21)/48

= 41/48

ii. 3(2/5) - 2(1/4)

= 17 - 9/4

= 68/20 - 45/20 

= (68 - 45)/20

= 23/20

iii. 12 x (-10)/3

= 4 x (-2)

= -8

iv 4(3/8) ÷ 25/18

= 7/4 x 9/5

= 63/20
