Question

1/3+2/3:x-1/8=1/2

Answer 1

\(\dfrac{1}{3}+\dfrac{2}{3}:x-\dfrac{1}{8}=\dfrac{1}{2}\\ \Leftrightarrow\dfrac{2}{3}:x=\dfrac{1}{2}+\dfrac{1}{8}-\dfrac{1}{3}\\ \Leftrightarrow\dfrac{2}{3}:x=\dfrac{12+3-8}{24}\\ \Leftrightarrow\dfrac{2}{3}:x=\dfrac{7}{24}\\ \Leftrightarrow x=\dfrac{2}{3}:\dfrac{7}{24}=\dfrac{2}{3}\times\dfrac{24}{7}=\dfrac{16}{7}\)

Answer 2

31​+32​:x−81​=21​⇔32​:x=21​+81​−31​⇔32​:x=2412+3−8​⇔32​:x=247​⇔x=32​:247​=32​×724​=716​

 

Answer 3

\(\dfrac{1}{3}\) + \(\dfrac{2}{3}\) : \(x\) - \(\dfrac{1}{8}\) = \(\dfrac{1}{2}\)

( \(\dfrac{1}{3}\) - \(\dfrac{1}{8}\)) + \(\dfrac{2}{3}\): \(x\)  = \(\dfrac{1}{2}\)

\(\dfrac{5}{24}\)      + \(\dfrac{2}{3}\) : \(x\) = \(\dfrac{1}{2}\)

               \(\dfrac{2}{3}\): \(x\) = \(\dfrac{1}{2}\) - \(\dfrac{5}{24}\)

                \(\dfrac{2}{3}\): \(x\) = \(\dfrac{7}{24}\)

                    \(x\)  = \(\dfrac{2}{3}\) : \(\dfrac{7}{24}\)

                    \(x\) = \(\dfrac{16}{7}\)

Answer 4

31​ + 2332​ : $x$ - 1881​ = 1221​

( 1331​ - 1881​) + 2332​: $x$  = 1221​

524245​      + 2332​ : $x$ = 1221​

               2332​: $x$ = 1221​ - 524245​

                2332​: $x$ = 724247​

                    $x$  = 2332​ : 724247​

                    $x$ = 167716​
