Question

10.2cm is rounded to one decimal place. Write down the maximum possible length it could have been.

Answer 1

Hey there,

So when you round a number the rule is if it is less than 5 you round down and of it is more than 5 or equal to 5 you round up right?

So the highest number it could have been is 10.019 because that’s the highest number you round up to get 10.2

Hope this helps
