Answer 1

Answer: x = 108

Given the below equation

x + 13 1/2 = 121 1/2

Firstly, we need to convert the mixed fraction into an improper fraction

`\begin{gathered} x\text{ + 13}(1)/(2)\text{ = 121 }(1)/(2) \\ 13(1)/(2)\text{ = }\frac{(2\text{ x 13) + 1}}{2} \\ 13\text{ }(1)/(2)\text{ = }\frac{26\text{ + 1}}{2} \\ 13(1)/(2)\text{ = }(27)/(2) \\ 121(1)/(2)\text{ = }\frac{(2\text{ x 121) + 1}}{2} \\ 121(1)/(2)\text{ = }(243)/(2) \\ \text{Therefore, the new equation becomes} \\ x\text{ + }(27)/(2)\text{ = }(243)/(2) \\ \text{Isolate x} \\ x\text{ = }(243)/(2)\text{ - }(27)/(2) \\ \text{Common denominator = 2} \\ x=\text{ }\frac{243\text{ - 27}}{2} \\ x\text{ = }(216)/(2) \\ x\text{ = 108} \end{gathered}`
