FInd the percentage of doublets between 1 and 100. Please detail the solution.
A "percentage" is simply a fancy way of writing a fraction over 100.
Comes from the Latin per centum = for every hundred.
67% = 67/100
It is that simple.
Here, it should be easy because the total number of numbers (from 1 to 100 inclusive) is... 100.
How many of those are doublets? There are so few numbers that you can simply count them:
11, 22, 33... 99 and (don't foget this one) 100 -- it has a "doublet of zeros".
The number of doublets (what you find = xx)
divided by
the total number of numbers (100)
is your fraction
it will look like xx/100
(where xx is the number you found)
Since this is already over a hundred, then that is directly your "percentage"
