1 and 1/3 + 3 and 1/3 + 5 and 1/3
11/3 and 12/3
2 and 1
1 1/2 + 1 1/2 = 3
2 1/2
1 1/4 and 1 3/4
10 + (-3) = 7 10 - (-3) = 13 10 and -3
The answer to your question is 10 and three.10 + 3 = 13 (Sum)10 - 3 = 7 (Difference)I hope this helps.
10
Three mixed numbers that add up to ten are 3 1/2, 3 1/4, and 3 1/4. When you sum these, you get 3 1/2 + 3 1/4 + 3 1/4 = 10. Other combinations are also possible, such as 4 1/3, 3 1/3, and 2 1/3. The key is that their total must equal ten.
11/3 + 12/3 = 3 (is one example only)
You know that sum of the first n whole numbers is n(n+1)/2. ( it is the same as the first n natural numbers since the zero does not add anything) So lets say you want the sum of all the whole numbers between 3 and 10. ( I made it easy to illustrate the idea.) The sum of the whole numbers between 0 and 3 is 3(4)/2=6 The sum of the whole numbers between 0 and 10 is 10(11)/2=55 So the sum of the whole numbers between 3 and 10 is the (sum of the whole number between 0 and 10) -(sum of whole numbers between 0 and 3) which is 55-6=49 So in general, for whole numbers m and n with m
1 1/2 + 1 1/2
