To see how 2/3 is larger than 21/30, it helps to put them in terms of the same denominator. To do this, we can multiply 2/3 by 10/10, which gives us 20/30.
Now it is easy to see that 21/30 is indeed larger than 2/3, which is equal to 20/30.

3x10=30
2x10=20, so 21 over 30 is a little bigger
Also
When you divide 21/30 you get 0.7 and when you divide 2/3 then you 0.66667 which shows that 21/30 is greater than 2/3
