Answer:

#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%#
