Question

if 1/2 = k, then can 2 be equal to 1/k

Answer 1

$\frac{1}{2} = k$

Then,

$\frac{1}{k} = 2 \\ = > \frac{1}{ \frac{1}{2} } = 2 \\ = > 2 = 2 \\ lhs = rhs$

Answer 2

${\red{\underline{\underline{\bold{Given:-}}}}}$

• $\frac{1}{2} = k$

${\blue{\underline{\underline{\bold{To\:Prove:-}}}}}$

• $\frac{1}{k} = 2$

${\green{\underline{\underline{\bold{Solution:-}}}}}$

$\frac{1}{2} = k \\ \\</p><p></p><p>By \:crisscross \:method \\ \\</p><p></p><p>\implies \frac{1}{k} = 2 \\ \\</p><p></p><p>\implies \frac{1}{\frac{1}{k}} = 2 \\ \\</p><p></p><p>\implies 2 = 2$

L.H.S = R.H.S

Hence, proved
