To make it easier, you can multiply the whole numbers by the denominators, and then add the numerator to the total. For the first one, do 4 x 10 = 40. Then add 5, and you get 45. The fraction will then be 45/10. For the second one, 1 x 10 = 10. Then add 7, and you get 17. The fraction will be 17/10.
Next, subtract the numerators because both of the denominators are equal. You then get 28/10 because 45 - 17 = 28.
Divide using long division. The whole number portion will be the number of times the denominator of the original fraction divides evenly into the numerator of the original fraction, and the fraction portion of the mixed number will be the remainder of the original fraction division over the denominator of the original fraction.
