Question

How do you convert 0.9 into a percent and fraction?

Answer 1

`0.9=9/10=90%`

Explanation:

A decimal fraction such as `ABCD.PQRST....` can be written as

`Axx1000+Bxx100+Cxx10+D+P/10+Q/100+R/1000+S/10000+T/100000+....` in fractionor simply

`ABCD+P/10+Q/100+R/1000+S/10000+T/100000+.............`

or `(ABCDPQRST)/(100000)`

In percentage it would be #(ABCDPQRST)/(100000)×100= (ABCDPQRST)/(1000)=ABCDPQ.RST#

As we have one digit in `0.9` immediately to the right of decimal point, it can be written as `9/10`.

To convert a fraction into percentage, just multiply it by `100` and percentage sign `%`. Hence

`0.9=9/10=(9/10xx100)%=90%`
