well I did 168 divided by 18 and got 9.33333 because that is the only family who doesnt smoke

I mean 47 my bad hold on

I got 3.57

ok sratch that I got 2.5 because I added 47 and 23

yeah and I got 5/12

Correct!

all you need to do is put 5/12 into a calculator, and it'll give you 5/12 in decimal form

What he said. ^^^^^

@atlantaslast How many decimal places are required in the answer?

two decimals places.

Then you will need to round up in this case.

how would that be? I just guessed and put 4.1 because it said 0.4166666

but it might be 1.6

Not really. ).416666666 rounded to two decimal places is 0.42.

so the answer would be 0.42?

Correct.

Thanks :)

you're welcome :)
