Question

What is 16+0.81 and show work

Answer 1

`16+0.81=16.81`

Since the number system we use is base ten, that means we can write each number as a sum of a number times ten to some power. In this problem we actually have:
`10^1+6*10^0+10^(-1)*8+10^(-2)*1=10+6+.8+.01=16.81`

Answer 2

16+0.81=16.81 and a way you can check your work is 16.81-0.81=16. You final answer is 16.81
