Lacey's milkshake recipe calls for $\frac{3}{5}$ of a scoop of ice cream, and Javier's recipe calls for $\frac{1}{2}$ of a scoop. How many more scoops of ice cream are used in Lacey's recipe than in Javier's recipe?

A. $\frac{1}{10}$ scoop
B. $\frac{1}{5}$ scoop
C. $\frac{1}{4}$ scoop
D. $\frac{2}{5}$ scoop

By converting both fractions (3/5 for Lacey's recipe and 1/2 for Javier's recipe) to have a common denominator of 10, we find that Lacey's recipe uses 1/10 scoop more ice cream than Javier's recipe, making the correct answer A. 1/10 scoop.

Explanation:

To determine how many more scoops of ice cream are used in Lacey's recipe than in Javier's recipe, we must compare the fractions. Lacey's recipe calls for 3/5 of a scoop, and Javier's recipe calls for 1/2 of a scoop. To compare these, we need a common denominator. The least common denominator for 5 and 2 is 10. So, we convert the fractions:

Lacey's recipe: 3/5 = 6/10 (by multiplying both the numerator and the denominator by 2)

Javier's recipe: 1/2 = 5/10 (by multiplying both the numerator and the denominator by 5)

Now we can subtract Javier's amount from Lacey's to find out the difference:

6/10 - 5/10 = 1/10

So, Lacey's milkshake recipe calls for 1/10 scoop more ice cream than Javier's recipe.

The correct answer is A. 1/10 scoop.
