In ¾ pound of a banana bread, there is ½ cup of cinnamon. How much cinnamon does the bread contain per pound?
Shkiper50 [21]

1 pound of bread contains \frac{2}{3} cups of cinnamon.

<h3><u>Solution:</u></h3>

Given that , In \frac{3}{4} pound of a banana bread, there is \frac{1}{2} cup of cinnamon

<em><u>To find:</u></em>

Amount of cinnamon per pound in bread

Let "n" be the cinnamon per pound present in bread

\frac{3}{4} pound of banana bread ⇒ \frac{1}{2} cup of cinnamon

Then, 1 pound of bread ⇒ n cups of cinnamon

Now, let us use criss cross method (i.e. multiplying the diagonal ordered terms and equating them)

\begin{array}{l}{\rightarrow n \times \frac{3}{4}=\frac{1}{2} \times 1} \\\\ {\rightarrow n \times \frac{3}{4}=\frac{1}{2}} \\\\ {\rightarrow n=\frac{1}{2} \times \frac{4}{3}} \\\\ {\rightarrow n=\frac{2}{3}}\end{array}

Hence, 1 pound of bread contains \frac{2}{3} cups of cinnamon.

VashaNatasha [74]
Hi,

Equation;

- 17 =  \frac{2y}{3}  +  \frac{3y}{4}

Solving:

- 17 =  \frac{2y}{3}  +  \frac{3y}{4}    \:  \:  \:  |  \div 12 \\  - 204 = 8y + 9y \\  - 204 = 17y \\ 17y =  - 204  \:  \:  \:  |  \div 17 \\  \\ y =  - 12 \:  \:  \:  \:  \:  \:  \:  \: (result)

Hope this helps.
