Fractions - how to find an unknown denominator

[lulurodmon]

I accidentally came to this video about something else. I really respect you math people.

I somehow fix my way through calculus. When I look at all of this math I don’t know how I was able to do it all. Such a fascinating thing is mathematics.

if the unknown is the denominator you could just use the reciprocals. e.g. 1/x = 4/20 then x/1 (which =x) = 20/4 (20/4 = 20 divided by 4)

When you have a fraction such as 1/4 with division line then 3/12 under how do you work this. Can't remember what this type if fraction is called

At 2:40. Instead of cross multiplying it would have been easier to flip the fraction upside down...
