look to the place next to it on the right and if its 4 through 0 round down and if its 5 though 10 round up
To the left
It is not clear where the factors came from!
the answer is 39 because when you round any number when its over 5 you round up and 1-4 you round down and because the 1st decimal place is fine you round to 10 and then because it goes to ten it makes it 39
10 th place
10% when expressed in decimal form is 0.1. The first decimal place right to the decimal is called a tenth
To the Right
You move the decimal point one place to the right.
The first and second places to the left of the decimal point respectively.
To estimate, you round the number to the nearest 10 and add, subtract, divide, or multiply. If the number is a decimal (ex. 12.132), you would round it to 12, and then round that to 10.
