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

Answer: 20

Step-by-step explanation:

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
