Question

A recipe calls for 5 1/2 cups of flour. Lorenzo only has 3 3/4 cups of flour. Write and slove an equation to find the additional amount of flour lorenzo needs to make the recipe.

Answer 1

1 3/4


5 1/2 - 3 3/4 = 1 3/4

Answer 2

Answer:

$x=1\frac{3}{4}$

Step-by-step explanation:

We are given that a recipe required flour=$5\frac{1}{2}=\frac{11}{2}$

Lorenzo has flour=$3\frac{3}{4}=\frac{15}{4}$

We have to find an equation to find the additional amount of flour Lorenzo needs to make the recipe.

Let x be the additional amount of flour  that is required to make the recipe

According to question

$x+\frac{15}{4}=\frac{11}{2}$

$x=\frac{11}{2}-\frac{15}{4}$

Using subtraction property of equality

$x=\frac{22-15}{4}$

$x=\frac{7}{4}=1\frac{3}{4}$

Hence, Lorenzo needs additional amount of flour to make recipe=$1\frac{3}{4}$
