Question

A recipe for chilie uses 2 1/3 cups of beans. Keith is making 1 1/2 times the recipe. Which equation helps keith find how many cups of beans he needs?

Answer 1

Answer:

$2\frac{1}{3} * 1\frac{1}{2} = 3\frac{1}{2}$

Step-by-step explanation:

Given that a recipe of chilie requires $2\frac{1}{3}$ cups of beans, to make $1\frac{1}{2}$ times the recipe, Keith would need x cups of beans.

Thus:

1 recipe = $2\frac{1}{3}$ cups of beans

$1\frac{1}{2}$ of the recipe = x cups of beans

$x*1 = 2\frac{1}{3} * 1\frac{1}{2}$

$x = \frac{7}{3} * \frac{3}{2}$

$x = \frac{7}{2}$

$x = 3\frac{1}{2}$

Therefore the equation that helps Keith find how many cups of beans he needs is: $2\frac{1}{3} * 1\frac{1}{2} = 3\frac{1}{2}$
