There is 75% decrease.
Step-by-step explanation:
Given,
Old value = 688 qt
New value = 172 qt
Change = New value - Old value
Change = 172 - 688
Change = -516 qt
The negative sign indicates decrease.
Decrease percent = ![\frac{Change}{Old\ value}*100](https://tex.z-dn.net/?f=%5Cfrac%7BChange%7D%7BOld%5C%20value%7D%2A100)
Decrease percent = ![\frac{516}{688}*100](https://tex.z-dn.net/?f=%5Cfrac%7B516%7D%7B688%7D%2A100)
Decrease percent = ![\frac{51600}{688}](https://tex.z-dn.net/?f=%5Cfrac%7B51600%7D%7B688%7D)
Decrease percent = 75%
There is 75% decrease.

============================================================
Explanation:
I'm assuming points M and N are midpoints of segments FD and FE respectively. If that's the case, then segment DE is twice as long compared to segment MN. We consider MN to be a midsegment.
So,
DE = 2*(MN)
3x-2 = 2*(x+4)
3x-2 = 2x+8
3x-2x = 8+2
x = 10
