you would keep the 12, and change the .13 into 13/100. 13 is prime, so it can't be simplified, and you would just leave it as 12 13/100 inches

12.13 = 12 13/100....the numbers to the left of the decimal are ur numbers greater then 1....the numbers to the right of the decimal are ur numbers less then 1, ur fractions. Notice the last number (3), it is in the hundredths place...so put it over 100...and then the whole number...giving u 12 13/100
