Question

A recipe for 12 cookies calls for 1 1/3 cups milk, 2 1/2 cups flour, and 1 3/4 cups other ingredients. How many cups of milk, flour, and other ingredients are needed to make 24 cookies?

Answer 1

Answer:

multiply all with 2

Step-by-step explanation:

Answer 2

Step-by-step explanation:

Given that:

• A recipe for 12 cookies needs 1 1/3 cups of milk, 2 1/2 cups of flour, and 1 3/4 cups of other ingredients.

To Find:

• How many cups of milk, flour and other ingredients are needed to make 24 cookies.

Process:

It has been provided to us the quantity of cups of milk, flour and other ingredients needed to make 12 cookies in the question. We have to find the quantity of cups of milk, flour and other ingredients needed to make 24 cookies. As 24 is clearly two times 12 so we can multiply all the quantities by 2 to get the quantities of cups needed for 24 cookies.

Solution:

Converting all mixed fraction into improper fraction,

$\sf{\longmapsto1\dfrac{1}{3}=\dfrac{(1\times3)+1}{3}=\dfrac{4}{3}}$

$\sf{\longmapsto2\dfrac{1}{2}=\dfrac{(2\times2)+1}{3}=\dfrac{5}{2}}$

$\sf{\longmapsto1\dfrac{3}{4}=\dfrac{(1\times4)+3}{3}=\dfrac{7}{4}}$

Multiplying all the quantities by 2,

$\sf{\longmapsto\dfrac{4}{3}\times2=\dfrac{8}{3}}$

$\sf{\longmapsto\dfrac{5}{\not\!{2}}\;\times\!\not\!{2}=5}$

$\sf{\longmapsto\dfrac{7}{\not\!{4}\;_2}\times\not{2}=\dfrac{7}{2}}$

Now,

Converting improper fraction into mixed fraction,

$\sf{\longmapsto\dfrac{8}{3}=2\dfrac{2}{3}}$

$\sf{\longmapsto\dfrac{7}{2}=3\dfrac{1}{2}}$

Hence,

To make 24 cookies quantity of ingredients needed is :

$\longrightarrow\;\sf{2\dfrac{2}{3} \;cups\; of\; milk.}$

$\longrightarrow\;\sf{5 \;cups\; of\; flour.}$

$\longrightarrow\;\sf{3\dfrac{1}{2} \;cups\; of\; other \;ingredients.}$
