Step by Step Explanation

The equation given is,


(1)/(8)+x=(1)/(6)

To find the value of x.

Solution,


\begin{gathered} (1)/(8)+x=(1)/(6) \\ \mathrm{Subtract\: }(1)/(8)\mathrm{\: from\: both\: sides} \\ (1)/(8)+x-(1)/(8)=(1)/(6)-(1)/(8) \\ \end{gathered}
\begin{gathered} (1)/(8)+x-(1)/(8) \\ =x \end{gathered}
\begin{gathered} (1)/(6)-(1)/(8) \\ \text{LCM of 6 and 8 :24} \\ \text{Factor 6 = 2}\cdot3 \\ \text{Factor 8 = 2}\cdot2\cdot2 \\ \mathrm{Multiply\: each\: factor\: the\: greatest\: number\: of\: times\: it\: occurs\: in\: either\: }6\mathrm{\: or\: }8 \\ =2\cdot\: 2\cdot\: 2\cdot\: 3 \\ =24 \end{gathered}
\begin{gathered} \text{Adjust the fraction based on LCM} \\ \mathrm{Multiply\: each\: numerator\: by\: the\: same\: amount\: needed\: to\: multiply\: its} \\ \mathrm{corresponding\: denominator\: to\: turn\: it\: into\: the\: LCM}\: 24 \\ \text{For 1/6 multiply denominator and numerator by 4.} \\ (1)/(6)=(1\cdot3)/(6\cdot4)=(4)/(24) \\ \text{For 1/8 multiply denominator and numerator by 3.} \\ (1)/(8)=(1\cdot3)/(8\cdot3)=(3)/(24) \end{gathered}

We Get,


\begin{gathered} =(4)/(24)-(3)/(24) \\ =(4-3)/(24) \\ =(1)/(24) \\ x=(1)/(24) \end{gathered}

So, the value of x is 1 / 24.
