31.346 round to the nearest hundredths and to the nearest ones

i believe it is 31.35

ones is: 31.

hundredths is: 31.35.

work:

the rule for rounding is pretty easy, if the number before you are trying to round up to is 5 or above, round up. if it is 4 or less, round down.

so, let's round 31.346 to the hundredths and ones place.

to start off, the hundredths place is two digits past the decimal, so you want to remove the thousandths place and either round up or down. let's check the thousandths place - is it higher or lower than 5? the hundredths place has a value of 6 - which is higher than 5 - so that means we round up.

so, your value for the hundredths place is: 31.35.

let's try this with the ones now. since we are removing everything after the decimal, we can look at the tenth's place -  is it higher or lower than 5? the tenths place has a value of 3 - which is lower than 5 - so that means we round down. (when doing ones, you don't go down a number, though. you stay at the same number, unless the value is greater than 5, in that case you round up a whole number.

so, your value for the ones place is: 31.

hope this helps and have an amazing day!
