2- reason larry and willa are each reading the same book. larry has read 2/3 of the book. willa said that she has read more than larry because she read 4/6 of the book. is willa correct? explain.

my son write- no because 2/3 and 4/6 are the same. if you have 1/3 and under it you put 2/6. and if you have 2/3 and you put 2 more under it will be equal.

check is this right or not #2 because #1 my son say he didn't get so please help him in #1 thank you
