Math question: How can the number 865 be represented as a sum of three consecutive integers?

Let's assume the first integer is x. Since we want three consecutive integers, the next two integers would be (x+1) and (x+2). Now, we can set up the equation: x + (x+1) + (x+2) = 3x + 3 = 865. Simplifying further, we have 3x = 862, and by dividing both sides by 3, we find x ≈ 287. Therefore, the three consecutive integers that sum up to 865 are 287, 288, and 289.

What is the sum of the digits in the number 865?

The sum of the digits in 865 is 19. To calculate this, add 8 + 6 + 5, which equals 19.

Math question: If 865 apples are equally divided among 5 baskets, with each basket receiving the same number of apples, how many apples will each basket have?

To find the number of apples in each basket, we divide the total number of apples (865) by the number of baskets (5). Using long division, we get: 173 ________ 5 | 865 0 ______ 865 -865 _______ 0 Therefore, each basket will have 173 apples.
