Answer: 20
Step-by-step explanation:
Let the unknown number be Z
So, four- fifths (4/5) of Z = 16
4/5 x Z = 16
0.8 x Z = 16
0.8Z = 16
Divide both sides by 0.8
0.8Z/ 0.8 = 16/0.8
Z = 20
Thus, the unknown number Z is 20
Four fifth means 4/5 = 0.8
Let the number be represented by x
From the question, 4/5 of x =16
0.8x = 16
Divide both sides by 0.8 to get the value of x
x = 16/0.8
x = 20
Therefore, 4/5 × 20 = 16
I hope this is clear, please mark as brainliest answer.

Thank you
f(x) = x² - x³
f(-2) = (-2)² - (-2)³
= 4 - (-8)
= 4 + 8 = 12
