Oh, dude, 90cm is like 0.9 of a meter. So, if we're talking fractions, that's 9/10 of a meter. But like, who really measures things in fractions anyway, right? Just know that 90cm is almost the same as a meter, but not quite.
1m = 100cm 25cm x (1m/100cm) = 0.25m
1/100
Oh, dude, it's like super easy! So, you've got 5cm, right? And you wanna express that as a fraction of 1m? Well, 1m is like 100cm, so 5cm is just 5/100, which simplifies to 1/20. Boom, fraction magic!

It could be 0.0013 kilometres.
