It depends on the circumstances. Sometime 0.8 (division by 2) is good, at others (division by 3) 0.75 is better.

14/15 hope this helps
what is 6.29892178 to the nearest 1 decimal place
1.724 to the nearest hundred is 0.
0.20
0.3
It depends what the benchmark is!
0.78 = 39⁄50
A decimal benchmark example would be 43 divided by 2. a decimal benchmark would be 42 divided by 2 because everyone knows that all even numbers are divisible by 2
It depends on the circumstances. Sometime 0.25 (multiplication by 4) is good, at others (division by 3) 0.3 is better.
1.9 Rounded to the nearest tenth
A benchmark fraction is the bar line in the middle of the fraction. :)

0.18 = 9/500.46 = 9/20 (approx)0.225 = 9/400.099 = 1/10 (approx).
The answer depends on which fractions you consider as benchmarks.
