Math question: Find the number of ways to arrange the digits in the number 445.

To find the number of ways to arrange the digits in the number 445, we can use the concept of permutations. Since all the digits (4, 4, and 5) are different, we can use the formula for permutations of distinct objects. The total number of ways to arrange distinct objects is given by n! (n factorial). In this case, the number of objects is 3 (as we have 3 digits), so we have 3! = 3 x 2 x 1 = 6 ways to arrange the digits. Hence, there are 6 different ways to rearrange the digits 4, 4, and 5 to form a three-digit number. These arrangements are: 445, 454, 544, 455, 545, and 554.

Math question: If I multiply a number by 5 and then subtract 45, the result is 445. What is the original number?

Let's call the original number x. According to the given information, we can write an equation as 5x - 45 = 445. To find x, we can isolate it. Adding 45 to both sides, we get 5x = 490. Dividing both sides by 5, we find that x = 98. Therefore, the original number is 98.

Math question: If the number 445 is multiplied by 3 and then divided by 6, what is the result?

To find the result, we can calculate: 445 multiplied by 3 equals 1335, and dividing it by 6 gives us 222.5. Therefore, the result is 222.5.
