Question

To bake muffins Matt needs X eggs for every 200 g of flour. If he used 900 g of flour, how many eggs did he use?

Answer 1

By proportion he used 900 * X / 200 = 4.5X eggs Answer

Answer 2

4.5x eggs are needed if he used 900 g of flour.

Explanation:

It is given that to bake muffins Matt needs X eggs for every 200 g of flour.

We need to find the number of eggs if he used 900 g of flour.

Let Matt needs Y eggs for every 900 g of flour.

Using proportion, we get

`(X)/(200)=(Y)/(900)`

On cross multiplication we get

`900x=200Y`

Divide both sides by 200.

`(900x)/(200)=Y`

`(9x)/(2)=Y`

`4.5x=Y`

Therefore 4.5x eggs are needed if he used 900 g of flour.
