Question

If$\frac{e}{f}=\frac{g}{h},$Which equation is correct

$\left(a\right).ef=gh$ $\left(b\right).eh=fg$$\left(c\right).eg=fh$

Short answer

The correct equation is,$eh=gf$ .

Step-by-step solution

Step 1. Given information.

The given equation is,

$\frac{e}{f}=\frac{g}{h}$

Step 2. Concept used.

If,$A\times B=C\times D$

Then,$AB=CD$

Step 3. Use cross multiplication. 

$\begin{array}{l}\frac{e}{f}=\frac{g}{h}\\ e\times h=g\times f\\ eh=gf\end{array}$

Therefore, the correct equation is,$eh=gf$ .
