Maths Question

[HongKongphooey]

I have an net amount of 134.40 of which 20% has been already been taken off, how do i calculate the original gross amount?
Not sure if this the right section but there isn't a maths section!

I don't think your inability to do maths has really much to do with this, HongKong. It's more to do with the way you were taught (or not) to think. Your problem is easy to solve with some thought. You have (100% - 20%) of the original sum, so you have 80%. If you divide what you have by 80 and multiply the result by 100 you are back to 100%.

I'm not criticising you. But it's not maths that you are short of.
