Answer: -1.1
Step-by-step explanation:
The given expression : -
[tex]\dfrac{1}{3}(21.69-24.99)[/tex]
To simplify the above given expression , we follow BODMAS (Bracket → Of → Diviide→ Multiply→ Add→ Subtract (A series of operation to perform )).
First we simplify the problem inside the bracket , we get
[tex]\dfrac{1}{3}(-3.3)[/tex]
Now, open Parenthesis or bracket , we get
[tex]\dfrac{1}{3}\times-3.3=-1.1[/tex]
Therefore, the final answer is -1.1 .
