Rounding to Thousandths 1 🔒

This quiz asks you to round 12 decimals to the nearest thousandth, keeping three digits after the decimal point.

A value such as 1.5684 or 164.7442 appears, and you trim it down to three places while watching the fourth digit closely.

The tricky part is that rounding up the third decimal can ripple into the digits in front of it, the same way 9.999 jumps to a cleaner number. Watching for that carry is what keeps these answers accurate when the digits are close to rolling over, and it is the main thing separating these from easier rounding tasks.

Recommended level: intermediate.
