divide 51 by 100 and add 2

Explanation:

#2##51/100# is a mixed fraction.
the fraction #51/100# is not a decimal,
to convert fractions into decimals divide the numerator by the denominator.

numerator = 51
denominator = 100

#51/100=0.51#

#0.51+2=2.51#

That means #2##51/100# = #2.51#

When converting fractions into decimal, the equation is #n/d#

#n# = numerator = 51
#d# = denominator = 100

#51/100=0.51#

Converting a mixed fraction into a decimal number is done by using the equation

#w+##n/d###

#w# = whole number = 2
#n# = numerator = 51
#d# = denominator = 100

#2+##51/100=2.51#
