Question #fcf83

Answer 1

Earl doubled (2x) the recipe.

Explanation:

`7 1/3 -: 3 2/3`

Begin by converting the mixed number into an improper fraction.

`3*7 +1 = 22` becomes `22/3`

`3*3 +2 = 11` becomes `11/3`

We now have a fraction division problem.

`22/3 -: 11/3`

When we divide fractions we multiply by the reciprocal.
Invert the second fraction.

`22/3 * 3/11`

`(cancel (22) 2)/cancel 3 * (cancel (11) 1)/cancel 3`

`2*1`

The recipe is two times greater. Earl has doubled the recipe.
