2 23/132 or in decimal 2.1742



Easiest way to solve this is to convert the length of wrapping paper into an improper fraction. So we have

24 3/4 = (4*24+3)/4 = 99/4



Now subtract the 5/6 feet of paper. First determine the common denominator for 4 and 6, which is 12. Then convert both fractions to the same denominator.



99/4 - 5/6 = 297/12 - 10/12 = 287/12



Now divide by 11 by simply multiplying the denominator by 11.

287/12 / 11 = 287/12 * 1/11 = 287/132



And finally convert from an improper fraction to a proper fraction.

287/132 = 2 23/132

In the equation z/6 =
Nikitich [7]

Hi there!  

»»————- ★ ————-««

I believe your answer is:  

"Isolate the variable  using inverse operations."

»»————- ★ ————-««  

Here’s why:

To solve for a variable, we would have to isolate it on one side.

To isolate it, we would use inverse operations on both sides on the equation until the variable is isolated.

There are no like terms in the given equation.

⸻⸻⸻⸻

\boxed{\text{Solving for 'z'...}}\\\\\frac{z}{6} = 36\\-------------\\\rightarrow (\frac{z}{6})6 = (36)6\\\\\rightarrow  \boxed{z = 216}

⸻⸻⸻⸻

Hope this helps you. I apologize if it’s incorrect.
