Answer: 9/1
Step-by-step explanation: We can write a ratio using the word "to", using a colon, or using a fraction bar.
The problem asks us to compare the number of
adult tickets to the number of child tickets.
We know that there are 45 adult tickets
and 5 child tickets so we have 45/5.
However, 45/5 is not in lowest terms so we divide
the numerator and denominator by 5 to get 9/1.
So the ratio of adult tickets to child tickets is 9/1.
