### Bruce's Scribepost, questions 12-13, Oct.17-09

Hey guys,

Last class Mr.Harbeck told us to answer the question we were assigned to answer. My questions were questions 12 and 13.

Question #12.

In a class of 32 students, there are 24 girls.

a) What is the boys to total students ratio?
Express the ratio as a fraction and a
percent.

Ratio - 8:32 boys to total

Fraction - 2 over 8 (I simplified the answer by dividing both numbers by 4,
8/4 = 2 and 32/4 = 8)

Percent - 25% (8 is 25 percent of 32 and 32 is 100% of 32 so 8+8+8+8 = 32. One eight is 25% of 32. 8/32 = 0.25( 0.25 x 100) = 25%.

b) What is the girls to boys ratio? Use
ratio notation to express the ratio.

8 : 24 boys to girls

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?

The team lost 12 games. ( 1. 7-4 = 3 2. 7 x 4 = 28 3. 3 x 4 = 12 games lost )

b) What was the team’s win–loss ratio?

16 : 12 win to loss ( I calculated the losses and got 12 and got 16 as the wins so 16+12 = 28 games)

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

Well I think 28 games plus 20 more win games the teams ratio would be

36 : 12 wins to loss
