How would I write 8.21 as a mixed number?
Really simple!
as an improper fraction it would look like this:
\(\frac{821}{100}\)
When changing it to a mixed fraction:
We divide the numerator by the denominator and keep the whole number to the side and leave the remainder as the numerator
the mixed number will look like this:
\(8\frac{21}{100}\)
we know that
A mixed number is a number consisting of a whole number and a proper fraction
so
we have
\(8.21\)
\(8.21=8+0.21=8+\frac{21}{100}=8\frac{21}{100}\)
therefore
the answer is
\(8\frac{21}{100}\)
