Question

Convert to the fractional equivalent and reduce 21.12

Answer 1

528/25

Step-by-step explanation:

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

Answer 2

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
`(2112)/(100)`.

Divide the numerator and denominator by 2:

`(2112)/(100)= (156)/(50)`

The numerator and denominator can be divided by 2 again:

`(78)/(25)`

There is no other common factor between numerator and denominator other than 1. Hence, it is the reduced form.
