Alex787 [66]

Answer:

$\frac{2}{25}$

Step-by-step explanation:

Given expression,

$\frac{\frac{2x-4}{30} }{\frac{15x-30}{18} }$

=> $\frac{\frac{2(x-2)}{30} }{\frac{15(x-2)}{18} }$

We see that $(x-2)$ is common in both numerator and denominator

hence canceling out we get:-

$\frac{2*18}{30*15}=\frac{2}{25}$

Answer= $\frac{2}{25}$

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

balandron [24]

<u><em /></u>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

<u><em>answer is 13/10 . . . it's positive</em></u>
