So I know of two different division methods, short and long. So my question is, I've got to work out questions quickly for a numeracy psychometric test coming up.
I will be dividing; decimals with whole numbers and percentages and fractions
Now the test I believe will be 16 minutes long and multiple choice, so I presume none of the questions will require long division but that is just a educated (obvious) guess. Now I know the long division method as shown in this video below, takes far to long for me to realistically answer any division sums in a short amount of time, I don't want to spend too much time on one question.
Baring in mind that it will be multiple choice, would I therefore be best just sticking with the division method below and when it doesn't come up with the exact answer just take some of the answer to choose one of the multiple choice answers?
SLEP Short division - YouTube
Now I've got one problem, I was on Youtube looking up how to divide decimals by whole numbers and one of the questions the uploader shown was.
A) Ms. Spencer buys her class a set of 4 travel games for $39.60. What is the cost per game?
I tried using the short division on this question and did not get exact answer or a finished answer.
$39.60/4 - 4 goes into 39 9 times remainder 1 so I put the 1 on top of the 6. 4 goes into 16 4 times exactly = $9.4, however the answer is 9.9 or $9.90 so that is an example where the short division method annoyingly does not work.
PLEASE HELP, just give me some advice on the question, it will be extremely appreciated, thank you.
