24 is the number because
2 + 4 = 6 and 24 ÷ 6 = 4
Reveres the digits and you get 42 which is 6 less than 48 which is 24 x 2.
18,27,81,etc.
Prime numbers that are still prime after their digits are reversed, like (13,31)(17,71)(37,73)(79,97)(107,701)(113,311)
A "decimal" can be any number which is not a while number - for example 3.4 or 0.7 If a number is divivded by any number less than 1, the result is a larger number. So that 5 divided by 0.2 = 25.0 and 4 divided by 0.5 = 8.0 ... which are greater than the original numbers But 5 divided by 2.2 = 2.2727 and 4 divided by 1.5 = 2.6667 ... which are less than the original numbers
The average is the sum divided by the number of original numbers. The sum of 132, 140, and 145 is 417. There were three original numbers, so the average is one-third of 417 or 139
All the two digit prime numbers that can be reversed are 11, 13 and 31, 17 and 71, 37 and 73, and 79 and 97.

A factor of a certain number in Mathematics are the numbers that can be divided by the original number.
Prime numbers that remain prime when their digits are reversed are called emirps. Some examples of emirps include 13 (31), 17 (71), 31 (13), and 37 (73). These numbers are interesting because both the original number and its reverse are prime numbers.

55 can be divided by 1, 5, 11, and 55. These are the factors of 55, which are numbers that can divide evenly into 55 without leaving a remainder. Factors are pairs of numbers that multiply together to give the original number, in this case, 55.
