Question

How do you find the result when 80 is decreased by 80%?

Answer 1

16

Explanation:

There are 2 methods: Either find 80% of 80 and subtract.

Or, in one step, find the 20% of 80 that would be left.

`80/100 xx 80 = 64 " "rArr " "80 - 64 = 16`

or: 100% -80% = 20%. Find the 20%

`20/100 xx 80 = 16`
