The first thing we'll do is to find how many percentage of their games have they actually won.
A. 10 WINS 6 LOSSES
So they played a total of 16 times
![(10)/(16) * 100\% = 62.5\%](https://img.qammunity.org/2019/formulas/mathematics/middle-school/47x40347akdec4pbtpm9h3vijrx9mbvis5.png)
note, the numerator (10) represents their 10 wins and the denominator (16) represents their total number of games played.
B. 13 WINS 7 LOSSES
They played a total of 20 games
![(13)/(20) * 100\% = 65\%](https://img.qammunity.org/2019/formulas/mathematics/middle-school/isqj7e3ia9kimw9x63pngw47d0zxcy5tmh.png)
C. 32 WINS 18 LOSSES
They played a total of 50 games
![(32)/(50) * 100\% = 64\%](https://img.qammunity.org/2019/formulas/mathematics/middle-school/7d44lqso5b302atcuwp9x420ggker4nwv6.png)
D. SIX WINS , 3 LOSSES
![(6)/(9) * 100\% = 66.6\%](https://img.qammunity.org/2019/formulas/mathematics/middle-school/dlimp8bgo13k68p3objilymbeka4s7m03h.png)
