Group 2 in LS2 have been revising on round numbers up to the billions.
Rounding is a useful skill to estimate. In this blog, we will be teaching you how to round. You need to know place values were you can find our example in our earlier blogs. To round you need a base number, I’ll pick a random one. (482.119) if rounding and you see a question asking to round to the nearest tenth you need to realise that the “th” means that it is in the decimal, not the whole number. in this number rounding to the nearest tenth would be the 1 after the 9 in the decimal place. due to the number being higher than 4, we round up. which is rounding to the nearest tenth. which would be 20 in this case. This would change the number to 482.120. I hope that this blog has taught you how to round.
