Chef Emerald had a recipe that called for 3/4 lb onions and 1 1/3 lbs of pork. He was preparing the recipe for a special event and needed to quadruple it to make enough for his guest. How many pounds of onions and pounds of pork would he need for the recipe?

We are given in this problem the recipe of a food specialty composed of 3/4 lb onions and 1 1/3 lbs of pork. In this problem, what is asked is the amount in pounds of onions and pork needed to become suitable to quadruple of the ordinary serving. The first thing to do in this problem is to add the two masses of ingredients. This is then expressed to

3/4 lb + 1 1/3 lb

1 1/3 is an improper function that is equal to 4/3. Thus,

3/4 + 4/3

we make the two fractions as similar fractions in which the denominator is equal to 12

9/12 + 16/12

we then add the similar fractions

25/12.

We need four times of this amount. This is equal to 100/12 or 8.33 lb
