which is the most accurate way to estimate 67% of 515?
\\(\frac{2}{5} \times 510\\) \\(\frac{1}{3} \times 510\\) \\(\frac{2}{3} \times 510\\) \\(\frac{3}{10} \times 510\\)

Explanation:

Step1: Convert percentage to fraction

We know that \(67\%\approx\frac{2}{3}\) (since \(\frac{2}{3}\approx0.666\) and \(67\% = 0.67\)).

Step2: Round the number

\(515\approx510\).

Answer:

\(\frac{2}{3}\times510\)
