#5/8=0.625#

Explanation:

To convert a fraction to a decimal, just divide the numerator by the denominator.

Since 8 is larger than 5, in order to divide, we must add a decimal point and some zeroes after the 5. We may not know how many zeroes to add but it doesn’t matter.

If we add too many we can erase the extras; if we don’t add enough, we can add more.

Sometimes, you may get a repeating decimal.
We can write the result using a bar over the repeating digit (or digits).

#0.625#

Explanation:

Decimals are a way of writing fractions which have denominators which are powers of #10#

#3/10 = 0.3#

#23/100 = 0.23#

#178/1000 = 0.178#

#8 xx 125 = 1000# so we can find an equivalent fraction for #5/8#

#(5xx125)/(8xx125) = 625/1000 = 0.625#
