Question

4/7 + 2/3 

5/6 - 3/4 

3/10 x 15/6

7/6 : 5/4

Answer 1

`4/7 + 2/3 = 12/21 + 14/21 = 26/21`

`5/6 -3/4 = 10/12 - 9/12 = 1/12`

`3/10 xx 15/6 = 3/10 xx 5/2 = 3/4`

`7/6 : 5/4 = 7/6 xx 4/5 = 14/15`

Answer 2

`4/7 + 2/3 `

`=12/21 + 14/21`

`=28/21`

`5/6 - 3/4 `

`=20/24 - 18/24`

`=2/24`

`3/10 x 15/6`

`=3/4`

`7/6 : 5/4`

`=7/6 xx 4/5`

`=14/15`

Answer 3

`4/7 + 2/3= 12/21 + 14/21= 26/21`

`5/6-3/4=20/24 - 18/24=2/24=1/12`

`3/10 xx 15/6= (3xx15)/(10xx6)=45/60=3/4`

`7/6 : 5/4= 7/6 xx 4/5= 28/30=14/15`
