Question

how do you divide numbers into decimals (without a calculator)?
e.g.
15 divided by 6

Answer 1

Well, 6 fits into 15 two full times.

So the answer will be 2 point something.

We have 3 leftover from teh 15, so that's 2 and 3/6

3/6 is half, so we get

2.5

Answer 2

:O thank you!

Answer 3

Think of highest common factors 15=5*3
6=3*2

15/6=5/2
=2.5

Answer 4

So what about a question like 18 divided by 30?

Answer 5

You will just have to do simplification.

18/30 = 9/15 = 3/5 = 0.6

Answer 6

18=6*3
30=6*5
18/30=3/5=6/10=0.6

Answer 7

its called long hand division:


?
----
6 | 15 ; what is the number 6(n) that is closest to, but is not
greater than, 15?

6(1) = 6
6(2) = 12
6(3) = 18 <- to big, go with '2'


2. ?
----
6|15.0000
-12 <- subtract 6(2) to get a new result to work on
------
30 <- bring down the next number, in this case '0'

now the strategy is to do the same step, try to find a
number, 6(n), that is close to but less than 30.

6(1)=6
6(2)=12
6(3)=18
6(4)=24
6(5)=30 <- an exact math, use '5'


2.5
----
6|15.0000
-12
------
30
-30 <- subtract 6(5) to get a new result
----
0 <- our new number is z zero which means we have
reached the end.

2.5 is our answer.

Answer 8

i spose 'less than or equal to' is better advice lol
