For Example: If you multiply both numbers by 10, get 7.9 and 72. 72 is greater than 7.9.
Also, 7.09 doesn't have any tenths, and tenths are greater than hundredths. However, 7.2 has tenths so we could tell that 7.2 is bigger than 7.09.

No, he is incorrect.
In the number line the numbers are arranged in ascending order from left to right,
Also, if we draw the number line in which,
1 unit = 0.01 ( shown below )
We observed that 7.09 is left from 7.20
7.09 < 7.20
7.09 is less than 7.20,
Hence, Ben is incorrect.
which one's greater? 7.20, which in it's original form 7.2
so 7.2 is greater.
7.2 is greater than 7.09 because the 2 in 7.2 could also be 7.20 which is greater than 7.09 and the more the numbers in the decimal world means it's less. decimals are fractions so the more the numbers the less the pieces. the nine in 7.09 is in the hundredths place and that's less than the tenths place and in fractions 7.09 would be 7 9/100 and 7.2 would be 7 2/10. two pieces from a ten cut pizza would be greater than a 100 cut pizza and eating 9.
