Question
In preparation for a picnic, Whitney made a salad with 1/2 of a bag of iceberg lettuce and 5/8 of a bag of Romaine lettuce. How many bags of lettuce did Whitney use in all?
Solution
To find out how many bags of lettuce Whitney used in all, we need to add the fractions of the iceberg lettuce bag and the Romaine lettuce bag she used.
Step 1: Identify the fractions to be added.
- Whitney used 1/2 bag of iceberg lettuce and 5/8 bag of Romaine lettuce.
Step 2: Add the fractions.
- 1/2 + 5/8
Step 3: To add these fractions, we need to have the same denominator. The least common denominator between 2 and 8 is 8.
Step 4: Convert the fraction 1/2 to have 8 as the denominator. We do this by multiplying both the numerator and the denominator by 4 (since 4*2 = 8). So, 1/2 becomes 4/8.
Step 5: Now, add the fractions 4/8 and 5/8.
- 4/8 + 5/8 = 9/8
So, Whitney used 9/8 or 1 1/8 bags of lettuce in all.
