Answer 1

`a, 51724 : 193 - 192`

` = 268 - 192`

` = 76`

`b, 9861 - 8304 : 346`

` = 9861 - 24`

` = 9837`

`c, 34/5 + 78/7 xx 14/39`

` = 34/5 + 2/1 xx 2/1`

` = 34/5 + 4`

` = 54/5`

`d, 1/2 - 1/3 - 1/6`

` = 3/6 - 2/6 - 1/6`

` = 0`

Answer 2

`a,51724:193-192   `

`= 268-192`

`=76`

`b,9861-8304:346`

`= 9861 - 24`

`= 9837`

 

`c,34/5 +78/7 xx 14/39`

 

`= 34/5 + 4`

 

`= 54/5`

 

`d,1/2 - 1/3 - 1/6`

 

`= (3-2-1)/6`

 

`= 0`
