Math Question: What is the result of subtracting 87 from 261 and then dividing the answer by 3, rounded to the nearest whole number?

To find the result, subtracting 87 from 261 gives us 174. Dividing this by 3 yields 58. Hence, rounding to the nearest whole number, the result is 58. This calculation can be shown through steps: 1. Subtracting 87 from 261: 261 - 87 = 174 2. Dividing the resultant 174 by 3: 174 ÷ 3 = 58 Therefore, the final answer after rounding is 58.

Math Question: What is the product when the number 261 is divided by 3, multiplied by 4, subtracted by 15, and finally added to the square of 9?

To solve this, let's break it down step by step. First, we divide 261 by 3 to get 87. Next, we multiply 87 by 4, which gives us 348. Then, if we subtract 15 from 348, we get 333. Finally, if we add the square of 9 (which is 81) to 333, we arrive at the answer of 414. Therefore, the product is 414.

Question: If a number is divisible by 29, 3, and 9, what is the largest possible multiple of 261?

To find the largest multiple of 261 that is divisible by 29, 3, and 9, we need to find the least common multiple (LCM) of these three numbers. The LCM of 29, 3, and 9 is 783. Now we divide this LCM by 261 to find how many times 261 fits into it. 783 ÷ 261 = 3. Therefore, the largest possible multiple of 261 is 3 times 261, which is 783. So 783 is the answer.
