Question

Eduardo has a recipe that uses 2/3 cup of flour for each batch. If he makes 4 batches, how many cups of flour will he need? How many cups of flour will he need in total if he makes 3 more batches?

Answer 1

4 batches:
`2(2)/(3)` cups

7 batches:
`4(2)/(3)` cups

Explanation:

If he uses 2/3 cup of flour for each batch, then that is 2/3 four times, or 2/3 · 4.

`(2)/(3)` ×
`(4)/(1)`

=
`(8)/(3)` =
`2(2)/(3)`

If he makes three more, than that will be 7 batches in total. We can multiply 2/3 by 3 to find out how much will be needed for those extra three, then add that product to
`2(2)/(3)`.

`(2)/(3)` ×
`(3)/(1)`

=
`(6)/(3)` = 2

`2(2)/(3) +2` =
`4(2)/(3)`

Thus,
`2(2)/(3)` and
`4(2)/(3)` are the answers.

hope this helps!
