Question
Solution 1
a) 40 cents : 1 dollar
First, we need to convert the dollar to cents because they need to be in the same unit to compare. 1 dollar is equal to 100 cents.
So, the ratio becomes 40 cents : 100 cents.
Both numbers can be divided by 20, so the ratio in lowest terms is 2 : 5.
b) 50 cm : 2.5 m
