I do not understand five through eight please help????????????

bogdanovich [222]

For number 5 the answer is 5/2
number 6 is 23/5
number 7 is 31/9

All you do is multiply the denominator by the whole number then the product of that you add that to the numerator and then the sum of that you just put that as your numerator and you keep the same denominator.
