63 and all its multiples.
1, 3, 7, 21.
3 & 7 (and of course, 1 and 21)
Example: Here are your numbers. 9/8 7/3 1/4 1/5 first, divide 9/8 by 7/3 for dividing, you flip the reciprocal for the second fraction and multiply. then, you divide your 1/4 by 1/5 Flip the reciprocal for the second and multiply.
To find the mean, you add all of the numbers and divide by how many numbers you added together. 7+2+3+2+1=15. 15/5=3. The mean is 3.
prime numbers that divide into 1155 = 3, 5, 7, 11
1 2 3 6 7 14 21 42.
1, 2, 3, 6, 7, 14, 21, and 42
To find the average of a number, first you add all the numbers that you want to average. Then you need to divide the sum of the numbers by the number of numbers there were. So if a set of numbers is 3, 5, 7, 1, 4, 7, 8 The equation would be 3+5+7+1+4+7+8=35/7(for the 7 numbers)=5
1. you add up all of the numbers that you have. And then you divide the number of numbers you had so if i did 6,5,7 i would do 6+5+7=18 then i have three numbers so divide 18 by 3=6 and that would be my answer
All Factors of 147:1, 3, 7, 21, 49, 147
Oh, what a lovely question! To find the average of those numbers, you simply add them all together and then divide by how many numbers there are. So, for 6, 7, and 8, you would add them (6 + 7 + 8 = 21) and then divide by 3 (since there are 3 numbers), giving you an average of 7.
They are: 3 and 7
