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 dose she use? (1 point)
To find the total amount of fruit Layla uses, we need to add the amount of oranges, apples, and grapes she uses.
1 1/2 cups of oranges is the same as 3/2 cups of oranges, since 1 1/2 is equal to 1 + 1/2.
So, Layla uses 3/2 cups of oranges.
Layla uses 2/3 cups of apples.
And she uses 3/4 cups of grapes.
Therefore, the total amount of fruit Layla uses is 3/2 + 2/3 + 3/4 cups.
To add these fractions, we need to find a common denominator. The common denominator of 2, 3, and 4 is 12.
Now, we can rewrite the fractions with the common denominator:
3/2 cups of oranges is equal to 6/4 cups (since 6/4 = (3/2) * (2/2) = 6/4).
2/3 cups of apples is equal to 8/12 cups (since 8/12 = (2/3) * (4/4) = 8/12).
3/4 cups of grapes is equal to 9/12 cups (since 9/12 = (3/4) * (3/3) = 9/12).
Adding the fractions with the common denominator, the total amount of fruit Layla uses is:
6/4 + 8/12 + 9/12 cups.
Adding the numerators (6 + 8 + 9) gives us 23.
So, the total amount of fruit Layla uses is 23/12 cups.
However, since 23/12 is an improper fraction (the numerator is greater than the denominator), we can simplify it.
Dividing 23 by 12 gives us a whole number of 1 and a remainder of 11.
Therefore, 23/12 is equal to 1 11/12 cups.
So, Layla uses 1 11/12 cups of fruit in her fruit salad. Answer: \boxed{1 \frac{11}{12} \text{ cups}}.
