Step-by-step explanation:

Given -:

One number is 25% more than another number

Sum of the two number = 135

Explanation -:

Let us assume the first number as x

Then,

Second number = x + 0.25

A. T. Q

x + x + 0.25 = 135

✎ 2x + 0.25 = 135

✎ 2x = 135 - 0.25

✎2x = 135 - 0.25

✎ 2x = 134.75

$\small{✎x = \frac{134.75}{2} = 67.375}$

First number = 67.375

Second number = x + 0.25

= 67.375 + 0.25

= 67.625

Check

67.375 + 67.625 = 135

Hence, verified

<u>Cold Farms: </u>

<u>Small box </u>

1 pint = $2.50

1 quart = $4.50

<u>Large Box</u>

1 quart = 2 pints .

2 pints = $4.50

1 pint = $4.50 / 2 = $2.25

<u>Cone Dreams:</u>

<u>Small box </u>

1 quart = $4.25 and

1 pint = $4.25/2 = $ 2.125

<u>Large Box</u>

1 gallon = $9.50.

1 gallon = 8 pints

8 pints = $9.50.

1 pint = $9.50 / 8 = $ 1.1875.

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

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)

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