Question

A recipe calls for 2 cups of milk every 6 1/4 Of flour. If you increase the flour to 43 3/4, how many cups of milk will you use?

Answer 1

14 Cups

Explanation:

43 3/4 = 43.75

6 1/4 = 6.25

43.75 % 6.25 = 7 x 2 = 14

Answer 2

For this case we have to convert the mixed numbers into fractions:

`6 \frac {1} {4} = \frac {4 * 6 1} {4} = \frac {24 1} {4} = \frac {25} {4}\\43 \frac {3} {4} = \frac {4 * 43 3} {4} = \frac {172 3} {4} = \frac {175} {4}`

We propose a rule of three:

2 milk ----------->
`\frac {25} {4}` flour

x -------------------->
`\frac {175} {4}`

Where "x" represents the amount of milk for
`\frac {175} {4}` cups of flour.

`x = \frac {\frac {175} {4} * 2} {\frac {25} {4}}\\x = \frac {\frac {350} {4}} {\frac {25} {4}}\\x = \frac {350 * 4} {25 * 4}\\x = 14`

Thus, 14 cups of milk will be used

Answer:

14 cups
