Question

add -13/14 + 1/4

Answer 1

Find the lowest common denominator between 4 and 14. This would be 28.

Answer 2

Then, multiply top and bottom by a number that gets the denominator to equal 28.

Answer 3

After that, all you have to do is add. :) (Make sure you don't add the denominators though)

Answer 4

so 7 and 4 ?

Answer 5

You would multiply 14 by 2 and 4 by 7.

Answer 6

and which ones do you have to add

Answer 7

-13/14 and 1/4, of course.

Answer 8

-13/14 = -26/28

Answer 9

1/4 = 7/28

Answer 10

-26 + 7 = ?

Answer 11

-19 is that the answer than

Answer 12

-19/28, yes.

Answer 13

Step 1: Find the lowest common denominator (LCM) for both numbers: 28
Step 2: Multiply both numbers by the number it takes for the original denominators to equal 28; (-13/14)*2 = -26/28 & (1/4)*7=7/28
Step 3: Add the new numbers together (take the top numbers first and add those together); -26+7= -19
Step 4: Put that number as the numerator, giving you the answer; -19/28.

Hope this helps. :)
