To subtract a fraction from any other number, both numbers need to be converted to fractions with the same denominator.
So, to subtract 34/5 from 7 we need to convert both numbers to fractions with 5 as the denominator.....
a) 3 x 5 = 15.
b) 15 + 4= 19
c) 34/5 = 19/5
d) 7 x 5 = 35
e) 7 = 35/5
f) 35/5 - 19/5 = 16/5
g) 16 / 5 = 3 and 1 remainder
h) 16/5 = 31/5
So, the answer is
i) 7 - 34/5 = 31/5

How do your borrow from a whole number when subtracting fractions?
A mixed number has a whole number and a fraction. A fraction is a number that is less than whole and that has a denominator underneath a numerator. To add or subtract mixed numbers, add or subtract the fractions, then add or subtract the whole numbers. If the fraction portion of a mixed number, such as 2 5/6, is more than the fraction portion of the mixed number you're trying to subtract from, such as 3 1/6, you must borrow from the whole number of the mixed number you're trying to subtract from to make its fraction bigger...
