beks73 [17]
<h2>Answer:</h2><h2>The answer is 32.464 for 23.54 less than 56.004</h2>

Step-by-step explanation:

23.54 less than 56.004 means,

Alexandra uses 12 cups of water and 6 cups of dry rice to make 18 cups of cooked rice. Today, she wants to make 4 cups of cooked
LekaFEV [45]

The proportion that Alexandra can use to find r is 9 cups of water and 4 cups of dry rice

If Alexandra uses 12 cups of water and 6 cups of dry rice to make 18 cups of cooked rice, this can be expressed as:

\frac{12}{6} = 18cups

To get the proportion "r" for the amount of dry rice to use to make 4 cups of cooked rice, we can write:

r = 4 cups

Divide both expressions:

\dfrac{\frac{12}{6} }{\frac{a}{b} } =\frac{18}{4}\\\dfrac{12b}{6a}=  \frac{18}{4}\\\dfrac{2b}{a} =\frac{18}{4}\\\frac{b}{a} =\frac{18}{8}\\\frac{b}{a}  =\frac{9}{4} =r

Hence the proportion that Alexandra can use to find r is 9 cups of water and 4 cups of dry rice
