Question

Hi Guys!
I need your help!
Please answer the above picture...
Please don't answer meaningless...

Answer 1

$\bf \: 1. \: \frac{3}{8} = \frac{375}{1000} \\ \\ \frac{3}{8} = \frac{125(3)}{125(8)} \\ \\ \frac{3}{8} = \frac{3}{8}$

$\bf \: 2. \: \frac{18}{54} = \frac{23}{69} \\ \\ \frac{18(1)}{18(3)} = \frac{23(1)}{23(3)} \\ \\ \frac{1}{3} = \frac{1}{3}$

$\bf \: 3. \: \frac{6}{10} = \frac{600}{1000} \\ \\ \frac{2(3)}{2(5)} = \frac{200(3)}{200(5)} \\ \\ \frac{3}{5} = \frac{3}{5}$

$\bf \: 4. \: \frac{17}{27} = \frac{25}{45} \\ \\ \frac{17}{27} = \frac{5(5)}{5(9)} \\ \\ \frac{17}{27} ≠ \frac{5}{9}$

So, from the above solutions, we found that except (iv) , all the equations are equal.

If any doubt, please ask :)
