Answer:

1.2 or 1 1/5

Step-by-step explanation:

To get the answer you have to divide 6/5. Once, I divide I should get 1.2 then you can keep it as a decimal (1.2) or a whole number fraction (1 1/5).

Therefore, your answers will be 1.2 or 1 1/5 (One and one fifths)

Tom's school report must be more than 12 pages, he writes at the rate of a half a page a day.
soldi70 [24.7K]

Answer:

24 days (or more)

Step-by-step explanation:

I assume you want to figure out how long it will take Tom to write the minimum amount of pages for his school report at that rate?

Since Tom writes 1/2 a page a day and he must write 12 or more pages, then it will take him 2 days to write one page, thus, 24 days to write 12 pages.

Therefore, Tom needs at least 24 days to write his school report.
