<u>ANSWER:</u>
4 batches of cupcakes can be made.
<u>SOLUTION:
</u>
Given, we need
cups of flour for each batch of cupcakes. And we have 17 cups of flour.
We need to find how many batches can be made.
1st way:
We will get the number of batches when we divide the available cups with cups required for one batch.
Available cups = 17 and required cups for one batch =
=
cups
number of batches = 

= 4.857
As the number of batches can’t be fraction, we will neglect the fractional part.
2nd way:
Let the number of batches be x.
Then, cups of flour required for batches must be less than available flour
(x)(
) < 17
(x)(7) < (2)(17)
7x < 34
x < 
x < 4.857
As the number of batches must be an whole number, x becomes 4.
Hence, 4 batches of cupcakes can be made.
