Answer:
2/9
Step-by-step explanation:
1) Use the first fraction rule, which is -a/-b=a/b, witch gives you
-10/21 / 15/7
2. Use the second fraction rule, which is a*d/b*c
Using a*d, b*c, you would get 10 x 7/21 x 15= 70/315
3. Simply our answer
Divide 70/135 by 35, witch would be 70 divided by 35/ 315 divided by 35, witch would be 2/9 , because 70 divided by 35 is 2 and 315 divided by 35 is 9.
