Question

What's 1,112,433 rounded to the nearest ten thousand?

Answer 1

`color(green)(1,110,)000` as the nearest 10,000

Explanation:

Compare this number to ten thousand `(10000 ->10,000 )`

`1,112,433 larr" The given value"`
`color(white)(1,1)10,000 larr" Compare to 10,000"`

Now look at the cut off point

`1,11color(red)(|)color(magenta)(2),433 larr" The given value"`
`color(white)(1,1)1color(red)(|)0,000 larr" Compare to 10,000"`

`color(red)(color(white)(...2/2)uarr)`
`color(red)("Cut off point")`

Consider the `color(magenta)(2)` to the right of the cut off point. As 1,112 is closer to 1,110 than it is to 1,120 we opt for the `color(green)( 1,110)` giving:

`color(green)(1,110,)000` as the nearest 10,000

Remember the rule: if 5 or more round up else round down. We rounded down
