no 3/7 = 27/63 4/9=28/63

It is: 1/7 of 63 = 9

9 = 3/7 x 21/1 = 63/7

We can convert both ninths and sevenths into a common fraction, by multiplying nine by seven, to get 63. So, 4/9 = 28/63 and 3/7 = 27/63. You can then easily see that 28/63 is exactly 1/63 larger than 27/63. So it is true, 4/9 is indeed greater than 3/7. Not much greater, but slightly greater.
