I assume we are solving for x see attachment.
Answer: Ratio of Parts
<u>Step-by-step explanation:</u>

The ratios are equal so the triangles are similar.
Answer:
A. what is the profit made by the retailer if he sells the article to the customer at the catalogue price?
10000
B.What profit is made by the manufacturer if the catalogue price is 50% above the manufacturing price?
25000
A.) There are many different expressions that can be equivalent to 4/2 and -2/3, but you just need one expression. <em>4/2 is equivalent to 2/1 and -2/3 is equivalent to -4/6.</em>
Reason:
There are two ways you can find a fraction equivalent to another.
1.) First one is by reducing the fraction if possible.
Example: <em>5/10=1/2, 10/30=1/3, 9/16=3/4.</em>
<em />
2.) The second one is by multiplying the numerator and the denominator by the same number, usually by 2 or 3.
Example: <em>1/2 x 2/2 = 2/4, </em> so <em>1/2= 2/4.</em> Another: <em>1/3 x 3/3 = 3/9</em>, so <em>1/3=3/9</em>
<em>That said, 4/2 = 2/1 because it was reduced. While -2/3 = -4/6 because it was multiplied by 2/2. </em>

The number is 5. All you have to do is make an equation based on the information you have, x will represent the missing number so, x to the power of 10 divided by x to the power of 7 is equal to 125, then solve.
