To find the decimal value equivalent of \( \frac{21}{25} \), we can perform the division:
\[ \frac{21}{25} = 0.84 \]
Now, we need to determine the nearest whole numbers that \( 0.84 \) is between. The two whole numbers closest to \( 0.84 \) are \( 0 \) and \( 1 \).
So, on the number line, you would plot the decimal \( 0.84 \) between \( 0 \) and \( 1 \). The two points you should mark are:
- 0 (the left endpoint)
- 1 (the right endpoint)
This means \( 0.84 \) is positioned just below 1, further confirming that it lies between these two points.
