No, a proper fraction has a numerator smaller than the denominator.
You do not!3 is a whole number, 7/3 is a fraction.If you multiply the whole number by the fraction you get 3*(7/3) = 7, which is larger not smaller.
One seventh is larger than one eighth. The smaller the number under a 1 in a fraction, the larger that fraction is. Think 1/4, 1/3, 1/2 and you'll see the size of the fraction increasing; the numbers are becoming larger.
If you're asking the difference, then a proper fraction is when the numerator is smaller than the denominator. And an improper fraction is a fraction bigger than whole or when the numerator is larger than the denominator.
A fraction of a fraction is yet another (usually smaller) fraction. For example 1/4 of 1/3 = (1x1) / (4x3) = 1/12 Only when both or one of the fractions is an "improper" fraction (larger than 1) does the multiplication give a result that is larger than the beginning fractions. For example : 7/4 x 3/5 = 21/20 = 1 1/20
