if there is 1 number to the right of the decimal, put that number over 10....not the whole number, just the number to the right of the decimal. Leave the number to the left of the decimal alone.
if there were 2 numbers to the right of the decimal, then put those two numbers over 100.
example :
3.43 = 3 43/100
2.76 = 2 76/100
if there were 3 numbers to the right of the decimal, put those 3 numbers over 1000
