Final answer:
9 can fit into 85 a total of 9 times because 9 x 9 = 81, which is the largest multiple of 9 that is less than or equal to 85.
Step-by-step explanation:
To find out how many times 9 can fit into 85 without going over, we will perform the following steps:
- Determine the largest multiple of 9 that is equal to or less than 85.
- Count how many times 9 fits into this multiple.
To find the largest multiple of 9 that does not exceed 85, we start by multiplying 9 by 1, then by 2, and so on, until the result is as close to 85 as possible without surpassing it. Multiplying 9 by 9 gives us 81, which is the closest multiple of 9 to 85 without going over. Therefore, 9 fits into 85 a total of 9 times.
Here's a quick review of the multiplication of 9 that proves this point:
- 9 x 1 = 9
- 9 x 2 = 18
- 9 x 3 = 27
- …
- 9 x 9 = 81
Any further multiplication would result in a number higher than 85, which is not allowed as per the question's instructions.
