Question

how is 4 over 5 equal to 0.8?

Answer 1

4 over 5 is a fraction.  So.......that would be this fraction ------> *4/5.* 

4/5 is a  not a *whole* number. it's 80% to a whole number. So if you convert it into a decimal form, you would get 0.8.

Answer 2

Okay, we know that $\frac{5}{5}$ is equal to 1. Now if we divide 1 by 5 to see how many times 5 can go into 1 we see that 1÷5 or $\frac{1}{5}$ = .2

So every $\frac{1}{5}$ is equal to .2

Now we can multiply the .2 by 4 to see what $\frac{4}{5}$ is equal to because $\frac{1}{5} *4= \frac{4}{5}$

And 4 * .2= .8
