Answer 1

A recipe for 15 corn muffins calls for 1 cup of flour. Hence 40 corn muffins can be made.

Solution:

Given, A recipe for 15 corn muffins calls for 1 cup of flour.

The number of muffins you can make varies directly with the amount of flour you use.

There are
`2(2)/(3)` cups of flour.

We have to find how many muffins can be made?

Now, according to the given information,

1 cup flour ⇒ 15 muffins

Then,
`2(2)/(3)` cups ⇒ “n” muffins

Now, by chris cross method,

`\begin{array}{l}{1 * n=15 * 2 (2)/(3)} \\\\ {n=15 * (3 * 2+2)/(3)} \\\\ {n=15 * (6+2)/(3)} \\\\ {n=15 * (8)/(3)} \\\\ {n=5 * 8=40}\end{array}`

Hence, 40 corn muffins can be made.
