GCSE-readyRounding and significant figures trainer
Round to decimal places (d.p.) or significant figures (s.f.). Look at the next digit: 5 or more rounds up.
Practice
Ten numbers to round. Keep any zeros that are needed, for example 2.0 to 2 significant figures.
Remember
- The first significant figure is the first digit that is not zero.
- Zeros at the start of a small number are not significant: 0.00305 to 2 s.f. is 0.0031.
- When rounding a whole number to significant figures, fill the places with zeros: 48 360 to 2 s.f. is 48 000.
