Question

How to round 43 to the nearest ten

Answer 1

43 to the nearest would be 40

Because, 3 is not greater than five in order to round it up by 1

Answer 2

40
when you round to the nearest 10, the rounding is based on the number next to it. 4 or less, it is 0. 5 or more round up to the next number.
Ex: round to the nearest 10 on 45

the next number is 50 because it is closer and you round up to the next number
