Final answer:
To find the ratio of cars to trucks in lowest terms, we divide both the number of cars (60) and trucks (72) by their greatest common divisor, which is 12, resulting in a simplified ratio of 5:6.
Step-by-step explanation:
The question involves finding the ratio of the number of cars to the number of trucks that Tommy has. Tommy has 72 toy trucks and 60 toy cars. To find this ratio in lowest terms, we first write it as 60:72. This ratio can be simplified by dividing both numbers by their greatest common divisor (GCD), which is 12.
Step 1: Divide the number of cars (60) by 12. 60 ÷ 12 = 5.
Step 2: Divide the number of trucks (72) by 12. 72 ÷ 12 = 6.
Therefore, the ratio of the number of cars to the number of trucks, in lowest terms, is 5:6.
