denominators. Then, solve your problem

Answer 1

In this real-world problem, we solve for the amount of flour needed to bake cookies using subtraction of fractions with unlike denominators.

Step-by-step explanation:

Real-World Problem:

Johnny wants to bake chocolate chip cookies for his friends. He has ¾ cup of flour, but the recipe calls for ⅔ cup of flour. How much more flour does Johnny need?

Solution:

To subtract fractions with unlike denominators, we need to find a common denominator. Here, we can multiply the denominators, yielding ¾ * 4 = ⅔ cup of flour. Subtracting ⅔ from ¾ gives us ¾ - ⅔ = ¾ - ⅔ = ¼ cup of flour. So, Johnny needs an additional ¼ cup of flour to make the cookies.
