Answer: He can make 16 batches of cookies.

Explanation:

Given: . To make cookies, Joshua needs
$1\frac18$ cups of flour per batch of cookies.

i.e. 1 Batch requires =
$1\frac18$ cups of flour

=
(9)/(8) cups [convert mixed fraction to improper fraction.]

Now if 1 batch =
(9)/(8) cups (i)

Then, 1 cup =
(8)/(9) batch. (ii) [Multiply (i) by
(8)/(9) ]

Joshua has 18 cups of flour.

That means , 18 cup =
18*(8)/(9)=2*8=16 batch. [Multiply (ii) by 18]

∴ He can make 16 batches of cookies.
