that depends on your restrictions. Do you want to include all integers in your sum? or perhaps just the natural number 1-5? So to answer the question, we need more info
Many things, but, as a fraction, it is equal to 7/5
Equal sums on both sides of the equation would be 29 + 29 = 58
Yes.
Many numbers can be expressed as the sum of two or more consecutive integers. For example, the number 15 can be written as the sum of consecutive integers in three different ways: 15=7+8 15=4+5+6 15=1+2+3+4+5 Look at numbers other than 15 and find out all you can about writing them as sums of consecutive whole numbers.
1/2 is equal to .5.
you can make at least 25 sums
2x4-3+5
Well, 1 is equal to 1. 9 is equal to 9. So any number from 0 to 9. I do not think this is what is meant by the question. If you mean any number with more than one digit. There is no such number. Because 11 sums to 2. 19 sums to 10. 21 sums to 3. 29 sums to 11. 111 sums 3. 119 sums to 11. The sums do not grow as fast the increase of digits.

Yes
Infinitely many. 12+11, 13+10, 14+9, ... , 22+1, 23+0, 24+(-1), 25+(-2), ... and then you have sums with numbers to one decimal place (dp) such as 11.6+11.4, and so on. Not forgetting numbers to 2 dp, 3, dp, 4, dp, ... , infinitely many dp. But these are only sums of two numbers. There are sums of 3 numbers, 4 numbers, ... infinitely many.
There is an infinite amount of numbers that can sum up to 24. Only 23, if you are just counting positive numbers.
1 + 3 + 6 + 8 = 18 = 2 + 4 + 5 + 7
No.
