153.9 inches is the correct answer
We are given:
There seems to be nothing I can do to simplify this equation. However, I can factor out an 
since they both have at least an . Here is what we get:
This is in the simplest form I can get into. I cannot do anything more to simplify this expression. This is your final answer.
I'll give a practice problem to help explain it a bit better.
Here, let's try to solve 45% of of 60.
First, we convert the percentage into a decimal. To turn any percentage into a decimal you move the point two spaces to the left.
That means 45% as a decimal is .45.
Next, we multiply our number, 60, by the decimal .45.
60×.45=27.
That means 45% of 60 is 27.
To sum it all up, you have to get the percentage, move the decimal point two spaces to the left, and multiply it by the number you were trying to find the percentage of.
Have a wonderful day! :)
