Question

15
2. Find the difference of the following:
1. 9/18 -3/18
2. 3 into 3/10 -1 into 7/15.​

Answer 1

Answer:

1). 9/18 -3/18

= 9 - 3/18

= 6/18.

2). 3 whole 3/10 - 1 whole 7/15

= 33/10 - 22/15 (you can take the L.C.M of 10, 15)

= 33×3/10×3 -22×2/15×2

= 99/30 - 44/30

= 99 - 44/30

= 55/30

3). 5 whole 3 /10 - 2 whole 2/15

= 53/10 - 32 /15 ( you can take the L.C.M of 10,15).

= 53 - 32/30

= 21 /30.

4). 6 whole 2/5 - 2 whole 4/10

= 32/5 - 24/10 ( you can take the L.C.M of 5,10).

= 32- 24 /10

= 8/10.
