sir i don't really comprehend how did you get rid of "d" in denominator ?

[@3minutemaths]

Hi ... to get rid of a denominator you need to multiply. It's the same as saying x/3 ,multiplied by 3, will just give you x. Here's a playlist with some more examples: th-cam.com/play/PLPglScc3TJ-P5n2EL254i655ImfAKcb0c.html. Hope it helps and all best S :-)
