Question
In preparation for a picnic, Ernesto made a salad with 1/2 of a bag of iceberg lettuce and 2/3 of a bag of Romaine lettuce. How many bags of lettuce did Ernesto use in all?Write your answer as a fraction or as a whole or mixed number.
Solution
Ernesto used 1/2 bag of iceberg lettuce and 2/3 bag of Romaine lettuce.
To find out the total amount of lettuce he used, you need to add these two fractions together.
First, find a common denominator for the fractions. The least common denominator for 2 and 3 is 6.
Rewrite the fractions with the common denominator:
1/2 becomes 3/6 (because 1 * 3 = 3 and 2 * 3 = 6)
2/3 becomes 4/6 (because 2 * 2 = 4 and 3 * 2 = 6)
Now, add the two fractions together:
3/6 (iceberg lettuce) + 4/6 (Romaine lettuce) = 7/6
So, Ernesto used 7/6, or 1 1/6, bags of lettuce in total.
