Step-by-step explanation:
gcd of all numbers
3,4,7,5,6,8
2 = 3,2,7,5,3,4
2 = 3,1,7,6,3,2
2 = 3,1,7,5,3,1
3 = 1,1,7,5,1,1
Answer:
7/12
Step-by-step explanation:
-15/9+9/4
We need to make them have the same denominator:
9x4= 36 so that is our new denominator
-15x4= -60
9x9=81
(Sorry if i dont make sense)
Now we have -60/36+81/36 which is equal to 21/36.
Now we simplify:
21/36=7/12
