Whenever you see a fraction ... like 9/100 ... it means a division problem.
A fraction means
(the top number) divided by (the bottom number) .
If you just pull out your pencil or your calculator and actually
do the division, the quotient you get is the decimal form of
the fraction.
If you divide 9 by 100, you get 0.09 .
So (1 and 9/100) is the same thing as 1.09 .
