Question

Which piece of string is longer 4/6 of a yard or 5/7 of a yard?

Answer 1

To answer this you must find the least common denominator
4/6times7=28/42
5/7times6=30/42
So 4/6=28/42 and 5/7=30/42 so 5/7 is bigger than 4/6

Answer 2

Well to find out you need to cross multiply, 7 x 6= 42 so thats the denominator now 7x4= 28 so 4/6=28/42, 6x5=30 so 5/7=30/42, which one is bigger? 30/42 a.k.a 5/7.
