In one week, Darell's family drank 1 1/2 cartons of regular milk and 1 2/3 cartons of soy milk. How much milk did they drink in all?Write your answer as a fraction or as a whole or mixed number.
Solution
To find out how much milk Darell's family drank in all, we need to add the amount of regular milk they drank to the amount of soy milk they drank.
They drank 1 1/2 cartons of regular milk. This is the same as 1.5 or 3/2 when expressed as a fraction.
They also drank 1 2/3 cartons of soy milk. This is the same as 1.67 or 5/3 when expressed as a fraction.
To add these two amounts together, it's easiest to use fractions:
3/2 (regular milk) + 5/3 (soy milk)
To add these fractions, we need to find a common denominator. The least common denominator between 2 and 3 is 6.
So we convert the fractions:
(3/2) * (3/3) = 9/6 (regular milk) (5/3) * (2/2) = 10/6 (soy milk)
Now we can add them:
9/6 (regular milk) + 10/6 (soy milk) = 19/6
So, Darell's family drank 19/6 cartons of milk in all. This is the same as 3 1/6 when expressed as a mixed number.
