First let us revise the rounding rules before getting down to the process of rounding :

• if the number you're rounding to is followed by a number from 0 to 4, then you drop that number.
• if the number you're rounding to is followed by a number that's 5 or more, you add 1 to that number.

∴

`\sf{763.9 \ to \ the \ nearest \ whole \ number :}\\\hfill\stackrel{\small\text{add 1 }}{3^(+1)}.\\\hfill\stackrel{\small\text{drop it}}{9}}`

∴

`\sf{763.9\approx764}`
