Answer:

#= 201 49/51#

Explanation:

You can write an equation using #x# for the number and then solve it ..

#51%# of some number is equal to #103#

#51/100 xx x = 103#

#x = (103xx100)/51#

#x = 201 49/51#

Or you can set up a direct proportion:

#51/103 = 100/x" "(larr"percent")/(larr"numbers")#

#x = (103xx100)/51#

#= 201 49/51#

As a decimal it is #201.96#, but this has been rounded off so it is not accurate.
