(Please correct me if I'm reading one of the numbers wrong.)
-5.8 + 2.6
We can rewrite this equation so it's easier to read like this:
2.6 - 5.8 (the answer will still be the same)
In the original equation, you're simply adding 2.6 to -5.8.
In the new equation, you're taking 5.8 away from 2.6.
An easy way to solve this is to ask "what's the difference between 5.8 and 2.6?", which is 3.2.
The answer to this problem is -3.2, because we're taking a larger number away from a smaller number.

Answer:
9/20 yes, 4/15 not. See below
Step-by-step explanation:
Pick 9/20 and multiply numerator and denominator by 5:
9/20 = 45/100
We know that if we divide a number by 100 we need to move the coma as two places left, so:
9/20 = 45/100 = 0.45
And this is a terminal decimal as we know where it ends.
On the other hand if we pick 4/15 let try to divide it (here I will do it 'manually'):
4 |_ 15
we can divide 4 by 15, so we use 40 and begin with a comma
40 |_ 15
0.
15 enters 2 times in 40 with a rest of 10, so:
40 |_ 15
30 0.2
100
100 divided by 15 is 6 and we have 10 as rest again, and again and again...
40 |_ 15
30 0.266.....
100
100
....
So, we will have 0.266666666666666 infinitely. The decimal for 4/15 is non terminating and is 0.26666666666666666...
