Answer:
0.8
Step-by-step explanation:
In this question you need to translate a fraction into a decimal.
Firstly you must focus on discovering the digit that you divide 100 by to get 5
100 / 5 = 20
Next, you must multiply both the denominator and multiplier by 20

5 x 20 = 100
This is 80%
We can then divide 80 by 100 to give us 0.8
