Kevin uses 2 and 1/4 cups of ravens for every half cup of peanuts when making a snack mix how many cups of raisins does Kevin us
Dmitrij [34]

Answer:

For 1 cup of peanut Kevin will use \frac{9}{2} \ cups \ \ \ OR \ \ \ 4\frac{1}{2} \ cups of raisins.

Step-by-step explanation:

Given:

\frac{1}{2} cups of peanuts = 2\frac{1}{4} cups of raisin

2\frac{1}{4}  can be rewritten as \frac{9}{4}

\frac{1}{2} cups of peanuts = \frac{9}{4} cups of raisin

We need to find number of cups of raisins used in 1 cup of peanut.

Solution:

Now we know that;

\frac{1}{2} cups of peanuts = \frac{9}{4} cups of raisin

So 1 cup of peanut = number of cups of raisins used in 1 cup of peanut

Now by using Unitary method we get;

number of cups of raisins used in 1 cup of peanut = \frac{\frac{9}{4}}{\frac{1}{2}}=\frac{9}{4}\times \frac{2}{1} = \frac{9}{2} \ cup \ \ \ OR \ \ \ 4\frac{1}{2} \ cup

Hence For 1 cup of peanut Kevin will use \frac{9}{2} \ cups \ \ \ OR \ \ \ 4\frac{1}{2} \ cups of raisins.
