Answer:
w = 2, z = 7
Step-by-step explanation:
If you have any questions about the way I solved it, don't hesitate to ask ;)
5/8 is more than 11/20
If we find the lower common multiple of the denominators which is 160 then we can multiply the top numerators by the opposite denominators
5x20=100
11x8=88
We now have
![\frac{100}{160} and \frac{88}{160}](https://tex.z-dn.net/?f=%20%5Cfrac%7B100%7D%7B160%7D%20%20and%20%20%5Cfrac%7B88%7D%7B160%7D%20)
The one on the left is simplified to 5/8 and the right is simplified to 11/20
The reason they cannot be added is because of 11 and 12. They are odd and even numbers and they have no link to each other. Because of this, you cannot add the exponents.
