You can find this out in any of the following ways:
1. Find a common denominator (multiplying the two denominators is one way - it need not be the LEAST common denominator). Convert the fractions to this common denominator. Then you can compare.
2. Use a calculator to convert the fractions to decimal, then compare. To convert to decimal, just divide the top part of the fraction by the bottom part.
4 1/7 (four and one seventh).
You need to make a common denominator. In this case the easiest would be 35 (7x5) Then 'what you do to the bottom you do to the top' 15/35 = 3/7 14/35=2/5 Therefore three sevenths is larger.
Ten sevenths or one and three sevenths
