Answer 1

`\Large \boxed{\mathrm{(a) \ 51\% }} \\ \\ \Large \boxed{\mathrm{(b) \ 41\%}}`

Explanation:

(a) To find the percentage of the students that are girls:

`\displaystyle \sf (total \ number \ of \ girls)/(number \ of \ students )`

`\displaystyle \sf (30+72)/(200 )= (102)/(200 ) =51\%`

(b) To find the percentage of students that prefer playing video games:

`\displaystyle \sf (total \ number \ of \ students \ that \ prefer \ playing \ video \ games)/(number \ of \ students )`

`\displaystyle \sf (30+52)/(200 )=(82)/(200) = 41\%`

Answer 2

(a) 51%

(b) 41%

Explanation:

We can simplify this problem down by realizing that the amount of girls over 200 will get us our percentage as a decimal.

Looking at this table, we can see that
`30+72=102` girls were asked. So,
`102/200=0.51`, and
`0.51\cdot100=51`.

We can also see that
`30+52=82` people preferred video games, so
`82/200=0.41`, and
`0.41\cdot100=41`.

Hope this helped!
