Answer 1

tats really difficult. well dont really try to divide make a table of the no u are r to divide by eg its 0.054 / 0.72 then 0.72 * 2= --- I mean make a table in the rough column. it might take long but its the easiest way IV found to divide decimal nos.

GOOD LUCK!

Answer 2

firstly, change all decimal into fraction....

0.054 / 0.72
54/1000 / 72/100

( in fraction, there is no division, so change division into multiplication and the fraction of 72/100 change into 100/72)
so the working will be like this,

0.054 / 0.72
54/1000 / 72/100
54/1000 x 100/72

(from here, you cancel out the zero evenly)...as so

0.054 / 0.72
54/1000 / 72/100
54/1000 x 100/72
54/10 x 1/72

(now, you divide 54 and 72 by 2, divide them to their lowest term as so....)

0.054 / 0.72
54/1000 / 72/100
54/1000 x 100/72
54/10 x 1/72
27/10 x 1/36 ( at this point, you have to divide 27 and 36 by 3)
9/10 x 1/12
3/10 x 1/4
3/40 (from here , you can convert the fraction into decimal)
0.075



1.2 / 0.078
12/10 / 78/100
12/10 x 100/78
12/1 x 10/78
6/1 x 10/39
60/39
1.538

Answer 3

1.) 0.054 divided by 0.72 You CANNOT divide by a decimal, so move the decimal to make it a whole number. It turns into:

0.054 divided by 72.

2.) Now, because you moved the decimal 2 places by the number you divided by, you gotta do it to the other number too. This turns into:

5.4 divided by 72

3.) At this point, I would use a calculator, but one is not handy. Divide. There's your answer.



***Just substitute the numbers for the second problem to get the set up for that problem!

Answer 4

Hello, here it goes.

The fist one:
0.054 / 0.72

since 0.054 is smaller than 0.72 you must add zeros to the answer, each zero that you ad in the answer is a zero extra you are putting in the 0.72.

So, the only way to make 0.72 smaller than 0.054 it must me 0.0072 that means 2 zeros, so the first part of the answer is 0.0

then try guessing numbers so multiplying it by 0.0072 it gives a number close but below 0.054, this number is 7

7 * 0.0072 = 0.0504
then
0.054 - 0.0504 = 0.0036

thats the new number you have to do the calculations with
but since 0.0036 is smaller than 0.0072 you must make the 0.0036 greater than 0.0072, but this time you do not add o erase any zeros to the 0.0072, you only add or erase at the begining.

0.036 is greater than 0.0072

0.036 / 0.0072 = 5
and
5 * 0.0072 = 0.036
0.036 - 0.036 = 0 (remainder zero, exact division)



First one done result 0.075
-------------------------------o------------------------------

With the second one now

1.2 is greater than 0.078 so we start right away

try out several numbers that multiplied by 0.078 is close but smaller than 1.2, in this case is 15.

15 * 0.078 = 1.17
1.2-1.17 = 0.03

since 0.07 is smaller than 0.078 you must add a decimal marker (comma) to the answer, so fa the answer is 15,xxxx

adding the decimal marker, you erase a zero in the remainder so it is now 0.3

0.3 is greater than 0.078 so we can continue

as before, a number multiplied by 0.078 that is close but smaller than 0.3, this number is 3 (so far 15,3xx)

3 * 0.078 =0.234
0.3 - 0.234 = 0.066

since 0.066 is smaller than 0.078 we take out one zero in the 0.066 making it 0.66 (remember we only add zeros to the answer the fist time we put the decimal marker)

a number multiplied by 0.078 that is close but smaller than 0.66 is 8 (so far the answer is 15,38x)

8 * 0.078 = 0.624
0.66 - 0.624 = 0.036

again... 0.036 > 0.078 so we make it 0.36
the number that multiplied by 0.078 that is close but smaller than 0.36 is 4

so here you have it. i did it in paper too, check the link.


Hope this helps

Answer 5

properly, first of all, your order of operations are off. you regularly do multiplication and branch formerly addition and subtraction. an person-friendly thanks to save in options order of operations is: Please (Parenthesis) Excuse (Exponents) My (Multiplication) expensive (branch) Aunt (Addition) Sally (Subtraction) So, first you may want to do 5.8/8.5. So, definite, flow the decimals over one to make it fifty 8 divided by technique of 80 5. once you divide fifty 8 into 80 5 elements, you don't get a adverse huge type, yet you do get decrease than a million, proper? imagine you've fifty 8 truffles and also you opt to diminish them up so as that 80 5 human beings get an equivalent quantity of cake - - each individual might want to get somewhat decrease than a million cake. (.sixty 8 (or about 2 thirds of a cake)) Make sense? So now, you've .sixty 8 then upload .70 and also you get a million.38. in case you meant to assert that the project is this: 5.8 / (8.5 +.07) then, for sure, you may want to do what's in the parenthesis first - - 8.5 +.07 = 9.2 Then 5.8 / 9.2 or fifty 8 / ninety 2 = .sixty 3 imagine of it in words of fifty 8 oz. of water it is sweet to pour both into ninety 2 cups. each individual might want to get a touch more effective than 1/2 of an oz. of water of their cup - or .sixty 3 oz. in preserving with cup. it is no longer adverse, merely decrease than a million entire ounce each and each. do not cry over math. i recognize it would want to correctly be complicated, inspite of the undeniable fact that it truly is amazingly logical and methodical. you merely opt to come across a fashion to imagine about it that it truly is wise to you. optimistically the cake or water get at the same time helped. in case you provide it a actual existence get at the same time, each now and then which could also help it make more effective sense. :-) Have an rather good evening!

Answer 6

0.72/0.054*0.068/1.2=13.333333333*0.056666666666666=0.755555555555555555

i am not sure this answer is correct,just try!

Answer 7

all you have to do is move the decimal and the do as usual
