Math question: What is the sum of all digits in the number 1380?

To find the sum of the digits in the number 1380, we add the individual digits together. The digit 1 + the digit 3 + the digit 8 + the digit 0 equals a sum of 12.

Math question: What is the sum of all odd numbers from 1 to 1380?

To find the sum of all odd numbers from 1 to 1380, we first find the number of terms using the formula (last term - first term)/2 + 1. In this case, the first odd number is 1 and the last odd number is 1380. Plugging these values into the formula, we get (1380 - 1)/2 + 1 = 690 odd numbers. The sum of an arithmetic series can be found using the formula: sum = (n/2)(first term + last term), where n is the number of terms. Plugging in the values, we have sum = (690/2)(1 + 1380) = 345 * 1381 = 475,245. Therefore, the sum of all the odd numbers from 1 to 1380 is 475,245.

Math question: The number 1380 is divisible by which digit from 1-9?

To determine which digit from 1-9 divides into 1380 evenly, we need to check if 1380 is divisible by each individual digit. Starting from 1, we check if 1380 ÷ 1 leaves no remainder. Since 1380 divided by 1 is equal to 1380 itself, 1 is a divisor of 1380. Continuing this process, we divide 1380 by 2, 3, 4, 5, 6, 7, 8, and 9, checking for remainders. From this investigation, we find that 1380 is divisible by the digits 1, 2, 3, 4, 5, 6, and 8. Therefore, 1380 is divisible by the digits 1, 2, 3, 4, 5, 6, 8, and 9 do not divide it evenly.
