how do you divide decimals by decimals?

Question

round the answer to the nearest hundredth

Answer 1

let's say you have to divide 139.4 by 2.05 you multiply both sides by 100 to make the decimal in the denominator disapear u will have 13940 divided by 205 the answer will be 68.

Answer 2

Change your decimals to whole numbers. Suppose you have N/D, which are any number, including decimals. So you are dividing N by D here.

To change D and N into whole numbers just multiply both the denominator (D) and the numerator (N) by some multiple of 10. Make sure you multiply both D and N by the same multiple; otherwise, you will get the wrong answer.

The reason this works is because when you multiply both D and N by the same number, you are really multiplying the N/D ratio by one (1.000). That's because Q/Q = 1; so, (NQ)/(DQ) = (N/D)(Q/Q) = N/D Q is the multiple of 10 (e.g., 10, 100, 1000, etc.) to make both decimals into whole numbers.

EXAMPLE: .333/.1 = (.333/.1) X (1000/1000) = (.333 X 1000)/(.100 X 1000) = 333/100 = 3.33; where our Q = 1000 so that both decimals become whole numbers

Answer 3

Move the decimal to the end. You may need to add zeros to the number your dividing, but you need to move both decimals the same number of times.

Answer 4

express the decimals in standard form

For a>b for a/b,

0.23/0.012 = (230 x 10^-3) / (12 x 10^-3)
= 230/12
=19.1

For a
0.029/0.25 = (29 x 10^-3) / (250 x 10^-3)
= 29/250
= 0.12

Answer 5

get rid of the decimals by suitably multiplying the Nr and Dr by multiple of 10
example
0.8967/0.00093
we have to multiply the Dr by 100000 to
get rid of the decimal.so multiply both the
Nr and Dr by 100000
so you have 8967/93 and successfully got rid of the decimals

Answer 6

I think your question can better be explained with an example ~ say 0.1/0.2
0.1 can be written as 1/10
similarly 0.2 can be written as 2/10 ie., 1/5

Now our problem can be written as (1/10) /(1/5)
= 1/10 * 5/1 = 1/2 = 0.5
