Question: What is the sum of all the odd numbers from 1111 to 200, inclusive?

To find the sum of the odd numbers from 1111 to 200, we need to determine the number of terms and then calculate the sum as follows. The first odd number in the given range is 1111, and the last is 199. By listing the odd numbers in ascending order (1111, 1113, 1115, ...), we can observe a common difference of 2. Using the arithmetic series formula: Sn = n/2 * (first term + last term), we can calculate the sum. The number of terms, n, can be found with the formula n = (last term - first term) / common difference. Plugging in the values: n = (199 - 1111) / 2 = -912 / 2 = -456. However, since n represents the number of terms, we take the absolute value, giving us n = 456. Now, using Sn = n/2 * (first term + last term), we have: Sn = 456/2 * (1111 + 199) = 228 * 1310 = 298,080. Therefore, the sum of all odd numbers from 1111 to 200 is 298,080.

Question: If the number 1111 is increased by 75% and then divided by 5, what is the resulting value?

To solve this, we first calculate 75% of 1111, which is 833.25. Next, we add this to 1111, obtaining 1944.25. Finally, dividing 1944.25 by 5 results in a value of 388.85. Thus, increasing 1111 by 75% and dividing by 5 gives us 388.85 as the resulting value.

Math question: What is the smallest four-digit number that is divisible by both 11 and 101?

To find the smallest number divisible by both 11 and 101, we need to find their least common multiple (LCM). Prime factorizing 11 and 101, we get 11 = 11 and 101 = 101. Since both numbers are prime, their LCM is simply their product: LCM(11, 101) = 11 × 101 = 1111. Hence, the smallest four-digit number divisible by both 11 and 101 is 1111.
