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.


Respuesta :

1 3/4


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

Answer:

[tex]x=1\frac{3}{4}[/tex]

Step-by-step explanation:

We are given that a recipe required flour=[tex]5\frac{1}{2}=\frac{11}{2}[/tex]

Lorenzo has flour=[tex]3\frac{3}{4}=\frac{15}{4}[/tex]

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

[tex]x+\frac{15}{4}=\frac{11}{2}[/tex]

[tex]x=\frac{11}{2}-\frac{15}{4}[/tex]

Using subtraction property of equality

[tex]x=\frac{22-15}{4}[/tex]

[tex]x=\frac{7}{4}=1\frac{3}{4}[/tex]

Hence, Lorenzo needs additional amount of flour to make recipe=[tex]1\frac{3}{4}[/tex]
