how many seconds is this written as a fraction

Answer 1

No...its 4/5 since 0.8 is 80/100

Answer 2

Answer: 8/10

Explanation: Using the place value chart, we can see that 0.8 means eight-tenths which can be written as the fraction 8/10. Since 8/10 is not in lowest terms, we need to divide both the numerator and denominator by the greatest common factor of 8 and 10 which is 2 to get 4/5.

Therefore, 0.8 can be written as the fraction 8/10.
