First, change the decimal to a fraction:  .2= 2/10

Then, write the mixed number:               2 2/10

Finally, change the mixed number to a fraction by multiplying the whole number (2) x 10 (the denominator of the fraction) and adding the numerator (2) to this number.  Place this over the 10 and you have your fraction:                                            22/10

[Always remember that decimals are just another way to write fractions.  One decimal place is 10ths, two places makes 100ths, three places 1000ths, and so on.  So, just place the number behind the decimal point over the correct multiple of 10 when you wish to convert a decimal to a fraction.]
