Remember, the digits after the decimal place are tenths, hundredths, thousandths, etc...

So .22 is 22 hundredths which is written as 22%2F100. So this means that 1.22 is the fraction 1%2622%2F100



1%2622%2F100 Start with the given mixed number

100%2A1=100 Multiply the denominator 100 by the whole number 1 to get 100

100%2B22=122. Add 100 to the numerator 22 to get 122. This final result is the new numerator

122%2F100 Place the new numerator over the same denominator

So the mixed number 1%2622%2F100 is equivalent to the improper fraction 122%2F100


So 1.22 can be written as 122%2F100
