Question

Jimmy ate 13 of his sandwich at lunch. He ate another 23 of the sandwich at dinner.
How much of the sandwich did Jimmy eat in all?

Answer 1

where did you learn how to type fractions?
1/3 + 2/3 = 3/3
He ate it all!

Or did you mean he ate 2/3 of what was left? In that case,
1/3 + 2/3 * 2/3 = 7/9

Answer 2

It’s 3/3. Some of you might think it is 2/3 but no, it says he ate ANOTHER not something like “he ate another and he had 2/3 left” so 1/3 plus 2/3 equals 3/3. You just had to add and look at the word of choice.
