Final answer:
None of the provided options A, B, C, or D are equivalent to the number 0.8. The equivalent representation in percentage form is 80 percent or the fraction 4/5, which is not listed in the options.
Step-by-step explanation:
The question is asking for the equivalent of 0.8 in a different form. The number 0.8 can also be written as 80 percent, since the decimal can be converted into a percentage by multiplying by 100. Additionally, 0.8 is the decimal form of the fraction 8/10, which can be simplified to 4/5. Looking at the provided options:
- A) 58 is just a two-digit number and not equivalent to 0.8.
- B) 8 + 5 is an arithmetic sum which equals 13, not equivalent to 0.8.
- C) 8.5 is a value ten times greater than 0.8.
- D) 85 is the percentage form of 0.85 and also not equivalent to 0.8.
None of the provided options A, B, C, or D are equivalent to 0.8. If we're talking about numerical value and representation, 80 percent would be the closest equivalent, but it's not listed as an option here.
