How to round decimals

How to round decimals? ok so if you want to round a decimal well first you have to know the number and the decimal behind it. Ok lets say the number behind is 43.78 ok so now you can leave the whole number behind for right now so now you look at the decimal .78 ok look in the hundredths place ok now see if the it is ABOVE 5 ABOVE 5 if it was above five you add another tenth to it and take away the rest behind it. In our question it was round 43.78 to the nearest tenth well if you use my theory it would be .78 rounded above 5 well its above 5 so you would add a tenth on and throw away the rest so it would be 43.8

Tenth??

tenthtenTH/noun

  1. constituting number ten in a sequence; 10th."the tenth century"
    • each of ten equal parts into which something is or may be divided.plural noun: tenths"a tenth of a second"

Hundredths?

a hundredth part, especially of one (1/100).the hundredth member of a series.Also called hundredth's place. (in decimal notation) the position of the second digit to the right of the decimal point.

Example 1

step 1. Round to the nearest tenth 65.39

step 2. look at the decimal .39

step 3. look in the hundredths place and its a 9

step 4. If it is above 5 which it is so you will take it off and carry it to the 3

step 5. look at the 3 so you carried the nine to add to the tenth so it will be 4

step 6. Ok so now add the pieces so it will be 65.4 instead of 65.39
