Question

0.64 to the nearest whole number

Answer 1

1 because 6 is bigger than 4,if it were 4 or under it would be 0 but it's not so the answer is 1

Answer 2

A whole number is a number that does not have a decimal point- e.g. 0, 1 2, 3 etc. 

When rounding a number, if the number after the one that is being rounded is greater than 4, the number is rounded up.  If not, it remains the same: 
6 is greater than 4.  Therefore, 0 is rounded up to 1. 

0.64 rounded to the nearest whole number is 1
