There are 77 different ways to add two positive whole numbers and get 155.
Here are a few of them:
1 + 154
20 + 135
55 + 100
64 + 91
77 + 78
9 and 8 if you add them.
63
-155
Add them altogether. 143+193+169+155+171+155 = 986 Now divide the sum by the amount of numbers you added, which is 6. You added 6 numbers to equal 986. 986/6=164.333. round that and you get 164. The mean of this group is 164
1, 5, 31, 155
155 + 155 = 310
1 x 155, 5 x 31 = 155
To find two numbers that multiply together to make 155, we need to factorize 155. The prime factorization of 155 is 5 x 31. Therefore, the two numbers that multiply together to make 155 are 5 and 31.
5*31=155
The mean is the same as average. You add up all the numbers in the set then divide it by how many numbers there are. for example: pretend the numbers are 4,2,7,5,2. to find the mean i add them all up. 139+2+7+5+2=155. now i divide. there are 5 numbers so 155 divided by 5 is 31. 31 is the mean.
Two numbers, 155 and 945, do not form a proportion.
