A 32 front 42 rear is the same as a 22 front and ??? rear?
32 .... I think 😕
could be 29 - too early!
28.9
(42/32) * 22 = ???
28.87. Not really gearing experts, just a bit of maths
If you need to ask, you can't push it...
when you have gear comparison questions and can't do maths, go here

I did look it up and one was 17 inches and one 19 inches.
What that means in the real world I don't know but I can stick my bike in a certain ratio (!) and know how that feels.
use the tool I linked above, it has visual comparison of where things are on scale, you can move cogs around and line stuff up to see what's equivalent
Depends what you mean by same.........

It means the distance travelled for one revolution of the pedal
not quite...
(it's the diameter of a directly-driven wheel, like a penny-farthing, or unicycle)
It means the distance travelled for one revolution of the pedal
thats metres development
yep for simplicity when your swapping on one bike
