Question #c181d

Answer 1

`75.448`

Explanation:

Given:`" "color(green)(75.447)color(red)(8)`

This is the same as:

`color(green)(75/1+4/10+4/100+7/1000)color(red)(+8/10000)`

We are looking at the `7/1000`

The trigger is: if the next numerator (decimal value) is less than 5 we do not change the 7 in `7/1000` and any digits to its right are considered as zero so we would have: `75.447`

However; the trigger value to the right of `color(green)(7/1000)` is `color(red)(8)`. As this satisfies the condition of 'equal to or more than 5' we round the 7 up by 1 digit. So we end up with:

`75.448`
