Rewriting decimals as fractions: 0.8

let's write 0.8 as a fraction so 0.8 the eight right over here is in the tenths place it is the tenths place so you could read this as 8/10 and we can write that literally as being equal to eight tenths or eight over ten and now we've already written it as a fraction and if we want we can simplify this down both 8 and 10 share common factors they're both divisible by two so let's divide both the numerator and the denominator by two we're not changing the value of the fraction because we're dividing by both the numerator and the denominator by the same thing 8 divided by 2 is 4 10 divided by 2 is 5 and we're done 8 or 0.8 is the same thing as 8/10 which is the same thing as 4/5
