A question may look something like this:
Round 8.765374847 to 2 decimal places/d.p.
And you'll be like:
- 2 decimal places means to have only 2 numbers after the point.
- .76 are those 2 numbers after the point.
- Look at the third number after the decimal point - it's 5.
- This 3rd number, in this case, is 5 or bigger
- So you take 8.76 and BOOST the 2nd number UP one.
You are now left with your answer rounded to 2 d.p.
