Question

The tennis team has won 10 matches and lost 5 matches. If the team continues to have the same ratio of wins to losses, how many wins will the team have after playing 45 matches?

Answer 1

30

Answer 2

10:5 = 2:1
total number of matches 10 + 5 + 45 = 60
so to keep the ratio the same
you need 40 : 20
but the team has already won 10 matches
so 40-10 = 30
so 30!

Answer 3

or

\[\frac{10}{15}=\frac{x}{45}\]

Answer 4

\[x=45\frac{10}{15}=30\]
