Let the common multiple be x
<span>3x : 2x </span>
<span>3x = 125 </span>
<span>x = 125/3 </span>

To find a 20 percent tip quickly, first find 10%, and then multiply it by 2.
Step-by-step explanation:
To find 10%, move the decimal 1 place to the left. So 10% of 53.82 is 5.382. Let's round that to 5.4 to simplify. Multiply it by 2 to get to 20% which is 10.8 and round to the nearest dollar to make $11.
The company would charge $837.50 to build the fence.
Installing a fence would cost $62.50 per hour.
It will take 13²/₅ hours to install this fence.
The cost would be:
<em>= Cost per hour x Number of hours taken </em>
Number of hours it would take should be converted to improper fraction to be multiplied:
13²/₅ = 67/5 hours
Cost is:
= 62.50 x 67/5
= $837.50
In conclusion, it would cost $837.50 to build the fence.

10 1/2x +2
- because you would add all the side lengths, so 2x+2x+ 3 1/4x+ 13 1/4x 1. You can combine like terms it to 10 1/2x+ 2.
