In order to do this we have to change it from a mixed numbers to an improper fraction. How we do this is by multiplying the whole number with the denominator, so for 2 5/8 you would multiply 2 and 8 together, getting 16. After doing this you add your product from your last calculation, 16, with the numerator, 5, to get the sum which is 21. You now take the sum, 21, and make that the denominator of the fraction, so replace 5 and put 21 there to get 21/8. Now follow these steps to find the improper fraction form of 1 3/8.
