See attachment for proper table

Solving (a): Students who spend more time playing games on tablets

To do this, we simply consider the playing games column.

The student are:

`Students = 192`

Solving (b): The percentage of boys.

From the same columns, the numbe of boys are:

`Boys = 138`

So, the percentage is:

`\%Boys = (Boys)/(Students)* 100\%`

`\%Boys = (138)/(192)* 100\%`

`\%Boys = 0.71875* 100\%`

`\%Boys = 71.875\%`

Approximate

`\%Boys = 72\%`
