Question

round 548.429 to the nearest tenth ?

Answer 1

you just need one decimal

Answer 2

The tenth position is the first number after the decimal place. To decide whether to round up or down, look at the next number. If it is 0-4, round down. If it is 5-9, round up.

Answer 3

ok, since it seems like this may be a point that you may want to remember,

the first spot after the decimal is the tenths.
the second spot is the hundredths
the third is the thousandths
the fourth is the ten thousandths, and so on

Answer 4

is it between the 54.

Answer 5

To 'round down', I mean keep the tenth position as it is. To 'round up' is to increase the value of the tenth position by 1.

Answer 6

54.8429

Answer 7

the 5 and 4 are before the decimal place. read it like you would a sentence from left to right.

Answer 8

so you have 548, which are before the decimal place, and you have 429 that are after.

since we only care about the ones that are after, we will ignore the 548 for now

Answer 9

looking at the .429, since we know that we are looking to round to the tenth's place and that is the first nmber after the decimal, we know we are looking to round the 4 either up or we want to leave it

Answer 10

to round the 4 we look at the number right after it. if it is 5 or greater we want to round up. if it is 4 or lower we want to round down.

Answer 11

since the number we have is 2, we know we want to round down. when we round down, everything after the 4 gets changed into a 0 and we don't change the 4.

Answer 12

so your 429 turns into 400

Answer 13

if we put that back where it belongs after the decimal point, we will get:

528.400

and since the zeros don't matter after that, we can chop them off and get:

528.4
