Question

1.

A recipe for pancakes requires 240g of oats. This makes 18 pancakes.
What quantity of oats is needed to make 24 pancakes?

Answer 1

Answer: 320 g

Explanation:

We can set up a ratio.

Let the amount of oats equal to x.

18/240 = 24/x

We can now cross multiply.

18x = 5760.

x = 320 g

Answer 2

`320\ g`

Explanation:

Start by setting up a ratio:

`\frac{\text{amount of oats}}{\text{number of pancakes}}=\frac{\text{amount of oats}}{\text{number of pancakes}}`

`\frac{240g}{18\text{ pancakes}}=\frac{xg}{24\text{ pancakes}}`

Cross multiply (Multiply the numerator of the first fraction by the denominator of the second and vice versa):

`240*24=18*x\\5760=18x\\\text{Divide both sides by 18}\\x=320\ g`
