To estimate 95% of 19, we can calculate \( 0.95 \times 19 \). However, since the options provided are expressed in terms of 20, we can compute \( 0.95 \times 20 \) and then compare to the given options.
- Calculate \( 95% \) of \( 20 \): \[ 0.95 \times 20 = 19 \]
Now, let's evaluate each of the options given:
-
\( \frac{4}{5} \times 20 \): \[ \frac{4}{5} \times 20 = 16 \]
-
\( \frac{19}{20} \times 20 \): \[ \frac{19}{20} \times 20 = 19 \]
-
\( \frac{1}{4} \times 20 \): \[ \frac{1}{4} \times 20 = 5 \]
-
\( \frac{3}{5} \times 20 \): \[ \frac{3}{5} \times 20 = 12 \]
From the calculations, the only option that yields \( 19 \), which is exactly \( 95% \) of \( 20 \), is:
\( \frac{19}{20} \times 20 \).
So, the most accurate way to estimate \( 95% \) of \( 19 \) among the given options is \( \frac{19}{20} \times 20 \).
