Question #2f963

Answer 1

`4 1/6` cups of sugar

Explanation:

The recipe calls for `1 2/3` cups of sugar, which we will convert to an improper fraction to aid multiplication:
`1 2/3 = ((3 times 1)+2)/(3) = 5/3`

If the recipe calls for `2 1/2` as much sugar, we need to find out what `1 2/3 times 2 1/2` is.
Again, we will convert the second mixed number into an improper fraction:

`2 1/2 = ((2 times 2) + 1)/(2) = 5/2`

Now, we multiply the two improper fractions:

`5/3 times 5/2 = (5 times 5)/(3 times 2) = 25/6`

And now we will convert back to a mixed number:

`25/6 = (24 divide 6)((25-24)/6) = 4 1/6` cups of sugar are needed.
