Question

A recipe calls for 3 2/3 cups of flour. Earl used 7 1/3 cups. By how much did he increase the recipe

Answer 1

3 2/3 =3.66
7 1/3 =7.33
7.33-3.66=3.77

Answer 2

Earl doubled the number of recipies due to amount of flour.

Explanation:

A recipe needs
`3\,(2)/(3)` cups of flour
`\left((11)/(3)\right)`, whereas Earl made use of
`7 \,(1)/(3)` cups
`\left((22)/(3) \right)`. The number of equivalent recipies is determined by simple rule of three:

`x = ((22)/(3) )/((11)/(3) )`

`x = 2\,recipes`

Earl doubled the number of recipies due to amount of flour.
