#9/20#

Explanation:

#.45# is the same as #45/100#.

#45/100# can be simplified: #45/100-:5/5=9/20#. there are no common factors (#(3*3)/(5*2*2)#), so this is as simplified as #45/100# can be.

45/100 or 9/20

Explanation:

#.45 = 45/100# This ratio can be reduced to

# 45/100 = (5 xx 9)/ (5 xx 20) # Dividing out common factors.

# (5 xx 9)/(5 xx 20) = 9/20#
