Answer:
Explanation:
Do you mean multiply?
- 8/15 * 20/24
- 8/15 * 5/6
5 and 15 have a common divisor -- 5
- 8/3 * 1 / 6
8 and 6 can be divided by 2.
-4/3 * 1/3
-4 / 9
====================
You could do the same thing without cancellation.
-8/15 * 20/24 = -160 / 360
Now you can divide by common factors. Start by dividing top and bottom by 10
- 16 / 36 Now divide top and bottom by 4
- 4 / 9
