Question

which is the most accurate way to estimate 45% of 61?
\\(\frac{7}{20} \times 60\\) \\(\frac{2}{3} \times 60\\)
\\(\frac{9}{20} \times 60\\) \\(\frac{13}{20} \times 60\\)

Explanation:

Step1: Convert percentage to fraction

We know that \(45\%=\frac{45}{100}=\frac{9}{20}\).

Step2: Estimate the number

\(61\approx60\).
So, \(45\%\) of \(61\) can be estimated as \(\frac{9}{20}\times60\).

Answer:

\(\frac{9}{20}\times60\)
