Answer:
16 year olds had the higher ratio of black belts to brown belts.
Step-by-step explanation:
15 year olds: 8/28 students had black belts
8/28 = 28.6% had black belts
16 year olds: 10/27 students had bald belts
10/27 = 37.0% had black belts
25a ^4 b^4 y^10 all of them are multiplied to each other I just separated it so it didn’t look confusing
168/4 to get the bike and the accessories to get 42
42x3=126
Since it’s a 10 team league and each team plays with the other team twice then 10+10=20, thus there would be 20 games played
