71/4 = 29/4
7 1/4 = 7 + 1/4 So lets add them together, remember we need both terms to have the same denominator
7 + 1/4 = 7/1 x (4/4) + 1/4 = 28/4 +1/4 = 29/4
==> 7/4
one and one-fourths is equal to five-fourths
If you multiply the fraction three-fourths by two you will get six-fourths. If you change that improper fraction to a mixed fraction you will get one and two-fourths. The two-fourths reduces to one-half. There fore three-fourths times two is one and a half.
625/100 or 25/4
It's probably easiest to first write that as an improper fraction and then add them:7/4 + 7/4 = 14/4 or 3¼
four and one third as an improper fraction = 13/3
4 1/3 as an improper fraction = 13/3
46/5
A fraction whose value is one or more is called an improper fraction, or a mixed fraction, depending on how you write it. For example one-and-a-half can be written as 1 1/2 - this is a mixed fraction. If you write it as 3/2, it is called an improper fraction.
One half and four fifths can't be written as improper fractions.
