-3-(-3)(-1)= 0, so 0 is the solution
Answer:
0.89898989.... is the correct answer

0.89898989.... is the correct answer because it can be written as
in the simplest form. and 0.89898989.... is rational because it is a repeating number.
Any rational number is a number that can be written as a fraction, a repeating decimal, a whole number, an integer, etc. As long as the number is a number with infinite digits like π.
This is the same as averaging. You add them and divide by 2.
((m/n) + (p/q))/2 would be a number in between m/n and p/q.
Do note that n and q must be nonzero, but luckily that is a given.
-2(-10)+5(2)
20+10
