Example Question #3 : How To Divide Decimals
Divide:
Rewrite so that both are in fraction form.
Convert the division sign to multiplication, and take the reciprocal of the 2nd term.
Example Question #53 : Decimals
Order the following decimals from greatest to least:
0.999, 0.909, 0.990
0.909, 0.990, 0.999
0.909, 0.999, 0.990
0.999, 0.909, 0.990
0.990, 0.999, 0.909
0.999, 0.990, 0.909
0.999, 0.990, 0.909
The greatest is 0.999 (999/1000), then 0.990 (990/1000), finally 0.909 (909/1000).
0.999 > 0.990 > 0.909
Example Question #1 : How To Order Decimals From Least To Greatest Or From Greatest To Least
Place the following numbers in order from smallest to greatest:
When comparing decimals, move left to right, comparing the size of the tenths, then the hundredths, then the thousandths, etc….
Example Question #2 : How To Order Decimals From Least To Greatest Or From Greatest To Least
Arrange the following from least to greatest:
From least to greatest:
0.007 (), 0.07 (
), 0.08 (
), 0.9 (
), 1.33 (
and
), 1.44 (
and
), 14
Example Question #3 : How To Order Decimals From Least To Greatest Or From Greatest To Least
Put the following in order of least to greatest:
None of the other answers
None of the other answers
Begin by converting each fraction into a decimal:
Now we can put the decimals in order:
0.269, 0.27, 0.2788, 0.28, 0.3157
or:
No answer choice matches this order, so our answer is "None of the other answers"
Example Question #2 : Ordering
Order the following decimals from greatest to least:
With decimals, the larger number has a value in the larger spot (anything with a nonzero value in the tenths, is larger than any number with a 0 in the tenths and a digit in the hundredths, and so on). Thus the correct ordering starts with the decimal with the largest digit in the tenth spot, or .340.
After that there is only one with a nonzero value in the tenths spot, so .101 comes next.
Then there are only two that have nonzero values in the hundreths spot, and since 5 is larger than 1 the next two are .052 and then .011.
Finally, the smallest number is the one with zeroes in the tenths and hundreths spot so .009 is the smallest.
Thus resulting in,
Example Question #5 : Ordering
Order the following from least to greatest:
, equivalent to two-hundredths, is the least out of the collection.
, equivalent to twenty-hundredths, is the next highest.
, equivalent to twenty-five hundredths, is the next highest.
, equivalent to thirty-four hundredths, is the next highest.
Finally, the highest number is , equivalent to one hundred and eighty hundredths.
Example Question #1 : Ordering
Order the following fractions from least to greatest:
2/3, 3/4, 1/2
1/2, 2/3, 3/4
3/4, 1/2, 2/3
3/4, 2/3, 1/2
2/3, 1/2, 3/4
2/3, 3/4, 1/2
1/2, 2/3, 3/4
1/2 is the least, then 2/3, then 3/4.
Example Question #1 : Fractions
Place the following fractions in order from greatest to least.
This question can be most easily answered by converting the fractions into decimals first.
Example Question #2 : Fractions
Order the following fractions from least to greatest:
The most generic process of ordering fractions that can apply to all questions begins with finding the common denominator between all fractions, preferably the least common denominator. In this question, the LCD is 40. Therefore the fractions become: . From this point, we can simply arrange the fractions based upon their numerators. This becomes:
. The final step is to reduce the fractions to their original denominators, which becomes:
.
If you are comfortable and competent in quickly converting fractions to decimals, then there is a quicker method than what is described above. Simply convert each fraction to a decimal, organize the decimals, and then convert the decimals back to fractions. In this question we can convert to
. Then we can reorganize this to
and convert back to
.
When approaching this kind of problem, choose the method in which you are more comfortable working with. There is no sense in trying to save time by choosing a method that you are not comfortable with and increasing your risk of answering the question incorrectly.
