Question

I want to know How to do it

Answer 1

well. kilo-ohms meaning, kilo, or 1,000
and mega-ohms meaning, mega or 1,000,000

we know there are 1,000 ohms in in kilo-ohm
so.. 1000ohms/kilo-ohm
that fraction, we can flip it upside-down, if needed, the ratio remains,
or is good still, we do flip it, for the sake of cancelling units,
I'll show you in one sec

and we know there are 1,000,000 in 1mega-ohm
1,000,000 is really 1,000 kilo-ohm as well
so.. one could say 1,000kilo-ohm/1Mega-ohm

or upside down

so... let us use the 7130
`\cfrac{7130\Omega}{1}\cdot \cfrac{k\Omega}{1,000\Omega}\cdot \cfrac{M\Omega}{1,000k\Omega}\implies \cfrac{\boxed{?}}{\boxed{?}}`

remember to cancel out units as well
