• Did you know there's a easy way of remembering how to do it this is how I remember is 4 or less just ignore five or more add one more

Stay safe,
Aiden.
• My teacher taught us: five or more raise the score, four or less let it rest.
• so if I said that 34 rounding the nearest ten would be 40?
• no because 4 and under round down and 5 and up round up
• How would you go about explaining and rounding a number like 120 to the nearest 10?
• 120 rounded to the nearest 10 is 110

• So pretty munch 36 rounded to the nearest ten is 40 right?
• Yes, because 36 is closer to 40 than 36 is to 30.

Have a blessed, wonderful day!
• do you have to learn how to round to the nearest ten.?
and I know how to round.
• how do you anderstand the hint
• no , infinity can only be rounded to ex-infinity :)
• infinity is not round to any number
• I think I might have spotted a mistake in one of the pratice test questions. Here's the question:

Which number line highlights all whole numbers that round to 200 if we are rounding to the nearest hundred?

A) 150 and 240
B) 200 and 299
C) 150 and 249

The problem is that option A is considered INCORRECT. Shouldn't BOTH options A and C be correct? And actually, isn't 240 even closer to 200? Or am I doing something wrong?
