What is 31 over 8 as a mixed number?
31/8 is an Improper Fraction. To convert to a mixed number. Divide by '8' Hence 8)31 = 3 remainder '7' The '3' is the coefficient (LARGE) number and the '7' becomes the fraction 7/8 Hence 31/8 = 3 7/8
The sum of the digits of a two digit number is fourteen if the number represented by reversing the digits is subtracted from the original number the result is eighteen what is the original number?
86 8 + 6 = 14 86 - 68 = 18 The difference of a transposition (reversing the digits), is always divisible by 9. If you take the difference, in this case 18, and divide that by 9, your answer is 2. This will be the difference between the two digits (ie, 1 + 2 = 3, so transposing 13 and 31 results in a difference of 18. So does 24 and 42 or 35 and 53, etc). This helps you quickly solve the problem by taking one half of the sum of the digits (14), divide in half (7) and move 1 number in each direction (one being half of 2, the known difference between the digits) and you get 8 (7+1) and 6 (7-1). If your difference was 27, then the two digits would be 3 numbers apart (27 divided by 9 = 3) such as 14 and 41 or 25 and 52, etc. If the solution was 25 and 52: The two numbers add to 7 and the difference of the transposition is 27. The two numbers add to 7 - one half of 7 is 3.5 - move 1.5 (half of 3, 27/9) in either direction from 3.5 and you get your answer 5 (3.5+1.5) and 2 (3.5-1.5). Try it where the difference of the transposition is 36 (the difference in the digits will be 4) such as 37 and 73 or 48 and 84.
What is one of the four numbers where factorial n has n digits?
Factorial n, written n!, is equal to the product of all integer numbers between and including 1 and n. In other words, n! = 1*2*3*4...*n You could find all four numbers by brute force, evaluating the values of n! and counting the number of digits in each. This is tedious, but the first solution is easy: 1! = 1, which has one digit, so the criteria you established are met when n = 1. From the person who posted this: First of all, thanks for the quick answer. Second of all, I know that n can equal 1, but i need the other 3. Especially those that are under 31. 24 works.

What is the secret is prime number if it is greater than 25 and less than 50 and the tens digit is an odd number and the sums of the digits is less than 10?
The prime numbers between 25 and 50 are : 23 29 31 37 41 43 47However 2 and 4 (which appear in the tens place of 5 of these numbers) are not odd numbers.We are left with 31 and 37.The sum of digits of 37 is 10 which is not less than 10;but the sum of digits of 31 is 4 which is less than 10.So, 31 it is
