Answer 9

@HelpWithK12 @aspenmurillo

Answer 10

no 3/8 is not the answer. two negatives make a positive.

Answer 11

But it's one negative.

Answer 12

the subtraction counts as a negative.

Answer 13

UM so then what's the answer?

Answer 14

To subtract fractions, find the LCD and then combine.
Exact Form:
7
8
78
Decimal Form:
0.875

Answer 15

7/8

Answer 16

Im still confused but um thanks.

Answer 17

You must change the denominators. We see that the denominator 4 can turn to 8 so we multiply it by 2.

\(\huge\bf{-\frac{1}{4} \times 2 = -\frac{2}{8}}\)

When subtracting a positive with a negative you will add the two.

\(\huge\bf{\frac{5}{8} + \frac{2}{8} = \frac{7}{8}}\)

Answer 18

Oops meant `-1/4 x 2/2 = - 2/8`

Answer 19

to subtract fractions you need to find the common denominator, which you did. two negatives make a positive so basically when you're subtracting a number with a negative, you can just add them together.

Answer 20

So that the answer? - 2/ 8 low-key starting to make sense

Answer 21

no the answer is 7/8

Answer 22

No we turned `-1/4` into `-2/8` so we can simplify the two fractions.

Answer 23

That is what i did in the beginning. So i've had the right answer all along -_- but someone told me it wasn't

Answer 24

well they're wrong lol

Answer 25

xD thanks

Answer 26

when youre subtracting a positive with a negative, you just add them together\\\ example\[3/12 - (-1/12) = 4/12\]

Answer 27

no problem!

Answer 28

To subtract, add the opposite.

Example:
What is 6 - 8?
To subtract 8 from 6, add the opposite of 8.
The opposite of 8 is -8, so to subtract 8, you add -8 to 6.
6 - 8 = 6 + (-8) = -2

Another example:
Now let's subtract a negative number using the same rule.

5 - (-2)

To subtract -2, add the opposite of -2 which is 2.

5 - (-2) = 5 + 2 = 7

Answer 29

@alayrhi
What @mathstudent55 wrote will help you understand where you went wrong.
Please read and ask questions if necessary .

Answer 30

By using a common denominator. You already know that

\(\dfrac{5}{8} - (-\dfrac{1}{4}) = \dfrac{5}{8} - (-\dfrac{2}{8})\)

Now apply the rule above for the subtraction subtraction.
To subtract -2/8 from 5/8, add 2/8 to 5/8

\(\dfrac{5}{8} - (-\dfrac{1}{4}) = \dfrac{5}{8} - (-\dfrac{2}{8}) = \dfrac{5}{8} +\dfrac{2}{8} = \dfrac{7}{8} \)
