Charlotte makes crepes using [tex]\frac{5}{8}[/tex] cup of milk for every [tex]\frac{1}{2}[/tex] cup of flour. She wants to know the amount of milk she uses per cup of flour.

How much milk does Charlotte use per cup of flour?

[tex]\boxed{?}[/tex] cup(s) of milk per cup of flour



Answer :

To determine the amount of milk Charlotte uses per cup of flour, you can find the ratio of the amount of milk to the amount of flour. Here’s the detailed, step-by-step solution:

1. Identify the amount of milk and flour used:
- Charlotte uses [tex]\(\frac{5}{8}\)[/tex] cup of milk.
- Charlotte uses [tex]\(\frac{1}{2}\)[/tex] cup of flour.

2. Set up the ratio of milk to flour:
We want to find the amount of milk per cup of flour, so we set up the ratio as:
[tex]\[ \frac{\text{milk}}{\text{flour}} = \frac{\frac{5}{8} \text{ cup of milk}}{\frac{1}{2} \text{ cup of flour}} \][/tex]

3. Divide the two fractions:
When you divide fractions, you multiply by the reciprocal of the denominator. Thus:
[tex]\[ \frac{\frac{5}{8}}{\frac{1}{2}} = \frac{5}{8} \times \frac{2}{1} \][/tex]

4. Multiply the fractions:
[tex]\[ \frac{5}{8} \times \frac{2}{1} = \frac{5 \times 2}{8 \times 1} = \frac{10}{8} \][/tex]

5. Simplify the fraction:
Simplify [tex]\(\frac{10}{8}\)[/tex] by dividing the numerator and the denominator by their greatest common divisor, which is 2:
[tex]\[ \frac{10}{8} = \frac{10 \div 2}{8 \div 2} = \frac{5}{4} \][/tex]

6. Express the simplified fraction as a decimal:
[tex]\(\frac{5}{4}\)[/tex] can be converted to a decimal by performing the division:
[tex]\[ \frac{5}{4} = 1.25 \][/tex]

Therefore, Charlotte uses [tex]\(1.25\)[/tex] cups of milk for each cup of flour.
