Question

Simplify
9/5m - a/10k

Answer 1

I don't think you can really simplify it any further... The only thing I can think of is this:

1. Change the first fraction into 18/10m

2. Now change 18/10m into (18/m)/10

3. Change -a/10k into -(a/k)/10

4. Now add them together:

(18/m)-(a/k)

_________

10

It'd be a stretch to call that a simplification. I don't think it is possible.
