Math question: What is the sum of the prime factors of the number 1908?

To find the prime factors of 1908, we divide it by the smallest prime number, which is 2. 1908 divided by 2 equals 954. We continue dividing by the smallest prime factors until we can't divide anymore: 954 divided by 2 equals 477, 477 divided by 3 equals 159, and 159 divided by 3 equals 53. As 53 is a prime number, we stop dividing. The prime factors of 1908 are 2, 2, 3, 3, and 53. Finally, the sum of the prime factors is 2 + 2 + 3 + 3 + 53 = 63. Explanation: The process of finding the prime factors involves repeatedly dividing the number by its smallest prime factors until no more divisions are possible. This method helps identify the prime factors, which are the prime numbers that divide the given number exactly. Adding all the prime factors gives the sum of prime factors. In this case, the prime factors of 1908 are 2, 2, 3, 3, and 53. Their sum is 63.

Math question for the number 1908: If 50% of a number is 954, what is the number?

To find the number, we can set up the equation: 50% of x = 954 Converting the percentage to a decimal, we have: 0.50x = 954 Dividing both sides by 0.50, we get: x = 954 ÷ 0.50 Simplifying further: x = 1908 Therefore, the number is 1908. This can be verified by multiplying 1908 by 0.50, resulting in 954, which matches the given information.

Math question: If a rectangle has a length of 34 units and a width of 56 units, how many times does the number 1908 fit within the area of this rectangle? Solution: To find the area of the rectangle, we multiply the length by the width: 34 units × 56 units = 1904 square units. Since the number 1908 is larger than the area, it cannot fit perfectly within the rectangle. However, if we round down the area to the nearest multiple of 1908, it becomes 1904.

The number 1908 fits completely into the area of the rectangle (1904 square units) zero times, but it would be a close approximation at rounded down value of once. However, it won't fit perfectly in terms of whole multiples.
