Answer 1

Answer:

I would choose Rhian

Rhian won 10 out of 15 games = 10/15

                                                   = 66.6667%

Arabella won 6 out of 10 games = 6/10

                                                      = 60.0%

Answer 2

Given :- Rhian won 10 of the 15 games she played this year while Arabella won 6 out of the 10 games she played this year.

To Find :- If you were the principal of the school, which student would you choose ?

Solution :-

→ Total games played by Rhian = 15

→ Total games won by Rhian = 10

So,

→ Total % of games won by Rhian = (Total games won by Rhian × 100) / Total games played by Rhian = (10 × 100) / 15 = (200/3) = 66.67%

and,

→ Total games played by Arabella = 10

→ Total games won by Arabella = 6

So,

→ Total % of games won by Arabella = (Total games won by Arabella × 100) / Total games played by Arabella = (6 × 100) / 10 = 60%

now, as we can see that,

→ 66.67% > 60%

since success percentage rate of winning the game of Rhian is greater than arabella . Therefore i would choose Rhian .
