Fascinating Fact:

Meteorologists round temperatures to the nearest degree, so a “warm twenty” might really be 19.6 if you want to argue with the forecast.

In 11 Plus Maths, pupils learn to round numbers not only to tens or hundreds, but also to decimal places for accuracy. This skill is vital in science, measurements, and financial calculations, where precision matters.

Key Terms

Decimal Place: The position of a number after the decimal point that shows smaller parts of one whole.
Accuracy: How close a measured or calculated value is to the true value.
Significant Figure: A digit that contributes to the accuracy of a number, starting from the first non-zero digit.

Frequently Asked Questions (Click to see answers)

How do you round a number with decimals?

To round a decimal, look at the next digit after your chosen place value. If it’s five or more, round up; if it’s less than five, keep the number the same.

What is the difference between rounding and truncating?

Rounding adjusts the last digit based on the next value, while truncating simply cuts off digits without changing the remaining ones. Rounding is usually more accurate.

Why is rounding important in science and maths?

Rounding helps simplify results without losing meaning. Scientists, engineers, and statisticians use rounding to report data clearly while keeping it realistic and useful.
