Write Ratios in Simplest Form
A team won 12 out of 18 games. Find the ratio of:
b) wins to losses
First, find the number of losses:
18 – 12 = 6
Then write the ratio of wins (12) to losses (6) as a fraction.
÷6
÷6
Divide the numerator and the denominator by the GCF, 6.

The ratio of wins to losses is 2 to 1. This means the for every 2 wins the team had 1 loss or the team had twice as many wins as losses.

Write Ratios As Fractions
Express the ratio 6 days to 2 weeks as a fraction in simplest form.
The unit needs to be the same, so we have to convert 2 weeks to 14 days.
Then, divide the numerator and denominator by the GCF, 2.
Written in simplest form, the ratio is 3 to 7.
6 days2 weeks
6 days ÷ 214 days ÷ 2
= =37
