A/2.8 x 2.8<br> "A over 2.8 times 2.8"
Jobisdone [24]
A/2.8 • 2.8
Division and multiplication are opposite of each other, meaning they cancel out.
This means that a/2.8 • 2.8 is a.
No matter what a is equal to, the answer is a itself.
Once a is divided by 2.8, it is then multiplied by 2.8, bringing us back to the original value of a.

Answer:
a/2.8 • 2.8 = a

Hope this helps!
