How To Round 17 5/8 To The Nearest Whole Number
Verdich [7]
<span><u><em>Answer:</em></u>
18

<u><em>Explanation:</em></u>
To round a number to the nearest whole number, we would check the fraction part:
If the fraction is <u>less than</u> 0.5, then we would simply ignore the fraction
If the fraction is <u>equal to or more than </u>0.5, then we would add 1 to the whole number and eliminate the fraction.

<u>In the given , we have:</u>
</span>17  \frac{5}{8}<span>.

The fraction part is </span>\frac{5}{8}<span> which is greater than 0.5
This means that we would add one to the whole number (round it up) and eliminate the fraction.
Therefore, the answer would be 18.

Hope this helps :)</span>
