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 $2\frac{2}{3}$ 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, $2\frac{2}{3}$ cups ⇒ “n” muffins

Now, by chris cross method,

$\begin{array}{l}{1 \times n=15 \times 2 \frac{2}{3}} \\\\ {n=15 \times \frac{3 \times 2+2}{3}} \\\\ {n=15 \times \frac{6+2}{3}} \\\\ {n=15 \times \frac{8}{3}} \\\\ {n=5 \times 8=40}\end{array}$

Hence, 40 corn muffins can be made.
