Question

Sara is having a dinner party for four friends and needs to reduce the serving size of the meatloaf recipe. She uses the equation x/4=5. How many servings did the recipe originally make?

Answer 1

20 is the answer. Also 20/4 = 5

Since , x/4 = 5
x = 4×5 = 20.


Mark as brainliest please.....

Answer 2

$\sf{\underline{Given:}}$

Sara uses this equation $\implies$ $\boxed{\sf{\frac{x}{4} = 5}}$

$\sf{\underline{In\:order\:to\:solve\:this\:equation:}}$

We need to find the value of x. We can do this by using 'Inverse operation'.

$\sf{\underline{What\:is\:an\:Inverse\:Operation?}}$

⚫Inverse operation is an opposite operation, that undo each other.

⚫The four main mathematical operations are:

$\implies$ $\sf{\underline{Addition}}$

$\implies$ $\sf{\underline{Subtraction}}$

$\implies$ $\sf{\underline{Division}}$

$\implies$ $\sf{\underline{Multiplication}}$

⚫The inverse of:

$\implies$ Addition is subtraction & vice versa.

$\implies$ Division is multiplication & vice versa.

$\sf{\underline{Note:}}$ The opposite of division is multiplication.

$\sf{\underline{So:}}$

We need to multiply 5 by 4.

$\sf{ \frac{x}{4} = 5}$

$\sf{x = 5 \times 4}$

$\sf{x = 20}$

$\sf{\underline{Therefore:}}$

Answer: 20 servings.
