Question

A recipe calls for 2 1/2 Cups of flour and four eggs. If only three eggs are used, how many cups of flour should be used? Give your answer as a mixed number in simplest form.

Answer 1

The quantity of flour used with 1 egg to makes recipe is 1
`(7)/(8)` cups .

Explanation:

Given as :

The ingredients for the recipe calls for

The quantity of flour = 2
`(1)/(2)` cups =
`(5)/(2)`

The number of eggs = 4

Now, we apply unitary method :

∵ The quantity of flour used with 4 eggs to makes recipe =
`(5)/(2)` cups

So, The quantity of flour used with 1 egg to makes recipe =
`((5)/(2))/(4)` cups

∴ The quantity of flour used with 3 eggs to makes recipe =
`((5)/(2))/(4)` × 3 cups

I.e The quantity of flour used with 1 egg to makes recipe =
`(15)/(8)` cups

Or, The quantity of flour used with 1 egg to makes recipe = 1
`(7)/(8)` cups

Hence , The quantity of flour used with 1 egg to makes recipe is 1
`(7)/(8)` cups . Answer
