Question

1/2,4/9,7/18 in smallest to largest

Answer 1

7/18 is the smallest because half of 9 is 4.5 and 1/2 is a half. So it goes like this 7/18, 4/9, 1/2

Answer 2

Well, first of all you would have to find a common denominator between them, so that would be 18, so you would change the others to a denominator of 18, 1/2 would be 9/18, 4/9 would be 8/18 ans 7/18 would stay the same. So, then you would put them in order. First 7/18, then 8/18 and finally 9/18.  So without the common denominators, it would be 7/18, 4/9 and 1/2
