The question how much more indicates that it is a subtraction problem. To subtract the two fractions, you need to have the same denominators. In this case they do have the same denominator. Now you would just subtract the numerators. 5-1 = 4 so it would be 4/6 of an inch. This needs reduced to 2/3 inch.
Hope that helps.
Brainliest is always appreciated : )
