It rained #13/20# inches more on Monday than it did on Tuesday.

Explanation:

To make this easier, let's give a common denominator to each of the fractions:

#5/4=25/20#
#3/5=12/20#

Next, just subtract:

#25/20-12/20=13/20#

#13/20" inches more of rain on Monday"#

Explanation:

# 1 1/4 " is the same as "1+1/4" is the same as "4/4+1/4=5/4#

So we have:#"Monday's rain - Tuesday's rain" ->" "color(brown)(5/4-3/5)#

'~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~

Change these so that they have the same denominator (bottom number) of 20

#color(brown)("Multiply by 1 and you do not change the value")#
#color(brown)("but you can change the way it looks")#

#color(blue)(5/5=1 and 4/4=1)#

#color(brown)((5/4color(blue)(xx5/5))-(3/5color(blue)(xx4/4)))color(green)(" " ->" " 25/20-12/20 )color(purple)(" "=" "(25-12)/20)#

#" "color(red)(=13/20)#
