Hey there!
In order to convert a fraction to a decimal you have to DIVIDE the NUMERATOR (the TOP number) by the DENOMINATOR (the BOTTOM number).
The formula is:
a/b
= a ÷ b
= c
Whereas, “a” is your numerator, “b” is your denominator, & “c” is your decimal
Now that we have that information out the way we can answer your question.
4/5
= 4 ÷ 5
= 0.80
Therefore, your answer is: Option B. 0.8
Good luck on your assignment and enjoy your day!
