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?

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

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.

To find out how much of the sandwich Jimmy ate in total, you need to add the number of sandwich pieces he ate at lunch and dinner.

Let's first calculate the number of sandwich pieces Jimmy ate at lunch:

Jimmy ate 13 pieces at lunch.

Now let's calculate the number of sandwich pieces Jimmy ate at dinner:

Jimmy ate 23 pieces at dinner.

To find the total number of sandwich pieces Jimmy ate, add the number of pieces he ate at lunch and dinner:

Total = 13 + 23

Therefore, Jimmy ate a total of 36 pieces of the sandwich.
