QUESTION #13

A soccer team played 28 games and won 4 out of every 7 games. There were no tied games.

a) How many games did they lose ?

Since 7 can go into 28 four times then you could multiply 4 by 4 to get 16. 28 subtract 16 is 12 so that means they lost 6 games.

b) What was the team's win-loss ratio ? Explain how you got the answer.

The team's win ratio was 16:12 in lowest terms its 4:3.

I got the answer by taking the number of times they won and number of times they lost to make the ratio, I got it in lowest terms by dividing both numbers by 4 because they are both factors of 4.

c) If this trend continues, how many losses would you expect the team to have once they have won 20 games ?.

I would expect 15 losses because to get 20 wins you can multiply the lowest terms by 5 to get 20 so you can multiply the number of losses by 5 and you get 15.

I hoped you liked my blog if theres anything I did wrong please leave a comment :)

13b- Shouldn't the amount of losses be 12 then, not 6?
