The decimal point is placed after two digits starting from the end. For each decimal place, we can write the number divided by 100.
21.12 can be written as [tex] \frac{2112}{100}[/tex].
Divide the numerator and denominator by 2:
[tex] \frac{2112}{100}= \frac{156}{50}[/tex]
The numerator and denominator can be divided by 2 again:
[tex] \frac{78}{25}[/tex]
There is no other common factor between numerator and denominator other than 1. Hence, it is the reduced form.

528/25
Explanation:
21.12 equals to 2112/100 if we divide twice 2112 and 100 in 2 we have: 2112/100=1056/50=528/25
