QUESTION IS IN THE SCREENSHOT

Answer 1

Answer 2

Well to be honest I am not too sure so do not take my word strongly. However -7/30 = 0.23 and -7/6 + -5/6 = 2 which is the closest however I am still working with all the other equations.

Answer 3

I worded that wrong. Its far off aha.

Answer 4

1/5 + -5/6 = -0.63 which is getting closer..

Answer 5

1/5 + -3/5 = -0.4 .... -.-

Answer 6

This is all experimenting with addition of fractions.

Answer 7

The answer is -3/5 + 5/6

Answer 8

\[\frac{ -3 * 6 }{ 30 } + \frac{ 5 * 5 }{ 30 }\]
Denominators are equal so you combine the fractions
\[\frac{ -3 * 6 + 5 * 5 }{ 30 }\]
Now we multiply the numbers
-18 + 5 * 5
- 18 + 25 = 7
Denom is 30 so 7/30

Answer 9

Hope this helped! @alayrhi

Answer 10

By the way I found the LCD or least common denominator by multiplying 5 by 6 which equals 30

Answer 11

Which proceeds to adding the fractions based on the LCD

Answer 12

As shown above :D

Answer 13

Thank you :D

Answer 14

Sure thing.

Answer 15

Could you help with one more?

Answer 16

Is it the same thing?

Answer 17

the problem ask for -7/30
but follow the process given by @DivineSolar

Answer 18

The answer is 1/2 right?

Answer 19

Oh yeah just reverse what I had there to get the -7/30

Answer 20

Make it -5/6 + 3/5

Answer 21

no when you subtract a negative the net result is adding

Answer 22

Time to show you the process of how it stays negative.

Answer 23

\[\frac{- 5 * 5 }{ 30 } + \frac{ 3 * 6 }{ 30 }\]
Same thing combine.
\[\frac{ -5 * 5 + 3 * 6 }{ 30 }\]
-25 + 3 * 6
-25 + 18 = -7
-7/30
Apply the rule of fraction -a/b = - a/b

Answer 24

A negative and a positive make a negative.

Answer 25

1/2 I don't think so.

Answer 26

Alright lets go through this step by step.

Answer 27

Apply the rule -(-a) = a

Answer 28

To our current problem.

Answer 29

\[\frac{ 7 }{ 8 } - \left(\begin{matrix}-3 \\ 8\end{matrix}\right)\]

Answer 30

Apply the rule and tell me what you get ^^

Answer 31

A negative cancels out a negative and that rule has negatives so what happens to our problem?

Answer 32

Hello @alayrhi ?

Answer 33

Yes sorry i was afk

Answer 34

Please do what I asked above :)

Answer 35

Its fine :).

Answer 36

Um 4?

Answer 37

Nooo xD! as I said we are applying the rule of -(-a) = a > 7/8 - (-3/8) see how they have negatives in the exact same spot? Well the cancel each other out

Answer 38

Now we get 7/8 + 3/8 > Since the denominators are equal we add the numerators so 7 + 3/8 which = ?/8

Answer 39

10/8?

Answer 40

Yes so now cancel the common factor of 2 and tell me what you get

Answer 41

AKA how many times doe 2 go into 10 and 8 which is what canceling the factor of 2 out means.

Answer 42

does*

Answer 43

5 times in 10 and 4 times in 8..

Answer 44

Correct so what is our final answer?
