Question

A bag with 2 ½ ounces of peanuts can make ⅔ of a jar of peanut butter.

Answer 1

Given :

A bag with 2 ½ ounces of peanuts can make ⅔ of a jar of peanut butter.

To Find :

How many ounces of peanuts will it take for there to be one jar of peanut butter.

Solution :

$2\dfrac{1}{2}\ ounces = \dfrac{2}{3}\ jar\\\\\dfrac{5}{2}\ ounces = \dfrac{2}{3}\ jar\\\\1= \dfrac{15}{4}\ \dfrac{ounces}{jar}$

Now,

1 jar of peanut butter is made by :

$1\times jar \times \dfrac{15}{4} \dfrac{ounces}{jar}\\\\\dfrac{15}{4}\ ounces$

Hence, this is the required solution.
