Question

What is the anwser to 5/10 - (-8/10)? I really need to know if this fraction would be a negitive?

Answer 1

Subtracting a negative number really means to add it

Here's addition:
(1) + (1) = 2
(1) + (-1) = 0
(-1) + (-1) = -2
(-1) + (1) = 0

Here's subtraction:
(1) - (1) = (1) + (-1) =0
(1) - (-1) = (1) + (1) = 2
(-1) - (-1) = (-1) + (1) = 0
(-1) - (1) = (-1) + (-1) = -2


Here's your problem specifically:

(5/10) - (-8/10)

(5/10) + (8/10)

*since they have the same denominator, that stays the same, and you only have to add up numerators

(5 + 8)/10

13/10

answer is 13/10 . . . it's positive

Answer 2

$\frac{5}{10}-(-\frac{8}{10})= \frac{5}{10}+\frac{8}{10}=\frac{13}{10}=1\frac{3}{10}$
