Math Problem Statement

A pancake recipe calls for 3/4 cup of flour for each batch. You have 3 cups of flour and enough of the other ingredients to make six batches of pancakes. How many batches of pancakes can you make?

Solution

To solve this problem, we need to determine how many batches of pancakes can be made with the available amount of flour.

The recipe requires 34\frac{3}{4} cup of flour for each batch of pancakes. We are given that we have a total of 3 cups of flour.

Steps to solve the problem:

  1. Calculate the number of batches that can be made with 3 cups of flour:

    To find out how many batches we can make, we divide the total amount of flour available by the amount needed for each batch.

    Number of batches=Total flour availableFlour per batch\text{Number of batches} = \frac{\text{Total flour available}}{\text{Flour per batch}}

    Number of batches=3 cups34 cup per batch\text{Number of batches} = \frac{3 \text{ cups}}{\frac{3}{4} \text{ cup per batch}}

  2. Divide 3 by 34\frac{3}{4}:

    Dividing by a fraction is the same as multiplying by its reciprocal. So, we multiply 3 by the reciprocal of 34\frac{3}{4}, which is 43\frac{4}{3}.

    Number of batches=3×43\text{Number of batches} = 3 \times \frac{4}{3}

  3. Simplify the calculation:

    Number of batches=3×43\text{Number of batches} = \frac{3 \times 4}{3}

    Number of batches=4\text{Number of batches} = 4

So, with 3 cups of flour, you can make 4 batches of pancakes.

You have enough ingredients for 6 batches, but the flour limits you to making only 4 batches.

Tip:

When dividing by a fraction, remember that it is equivalent to multiplying by the reciprocal of that fraction. This can make solving problems involving division of fractions easier.
