Layla is making fruit salad. She uses 1 1/2 cups of oranges, 2/3 cups of apples, and 3/4 cups of grapes. How many cups of fruit does she use?
1. 3 /19
2. 3 7/12
3. 2 1/9
4. 2 11/12
To find the total amount of fruit Layla uses, you need to add together the amounts of each type of fruit she uses.
She uses 1 1/2 cups of oranges, which is the same as 1 1/2.
She uses 2/3 cups of apples.
She uses 3/4 cups of grapes.
To add these fractions together, you need a common denominator. In this case, the least common denominator is 12.
1 1/2 is the same as 3/2 or 18/12.
Now let's add the fractions:
18/12 + 2/3 + 9/12
To add these fractions, you need to find a common denominator. In this case, the least common denominator is 12.
18/12 + 2/3 + 9/12 = (18 + 8 + 9)/12 = 35/12
Therefore, Layla uses 35/12 cups of fruit.
This can be simplified to 2 11/12.
So, the correct answer is 4. 2 11/12.
