What type of number best describes 0.9 which is 3 times 0.3?
It is a rational number because it can be expressed as a fraction in the form of 9/10
At his job Peter fills out a time sheet every Friday This week Peter spent 27.5 hours out of 40 hours or 0.6875 of his time working on Project A Which fraction is the best estimate of the time P?
0.6875 = 11/16 To convert a decimal into a fraction, write the decimal divided by 1 (0.6875/1) and then move the decimal point all the way to the right of the decimal number to convert it into a whole number and add as many zeroes as there are numbers after the decimal to the number on the bottom: 0.6875/1 = 6875/10000, then simplify he fraction: 6875/10000 = 1375/2000 = 275/400 = 55/80 = 11/16 Alternately simply divide time spent(27.5) by total time (40) and get 27.5/40 then try to simplify. multiply by 2 you get 55/80 then divide by five 11/16

How do you change decimals to fractions or mixed numbers?
Let's say you have a decimal number that has a 0 at the left of the decimal point, (like 0.057), and you want to change it into a fraction. First take all the numbers to right of the decimal point (in this case 57, you can drop the leading 0's) and that will be your numerator (the "top" part of your fraction). For the denominator ("bottom" part) of your fraction, use a 1 followed by the same number of 0's as their are digits after the decimal point (in this case 3 -- here you must count the leading 0!). So 0.057 would be 57/1000 as a fraction. Decimal numbers that have numbers other than 0 the the left of the decimal point can be converted into mixed numbers. Just use the numbers the the left for the integer part of the number, and the same procedure as above to convert to a fraction part. Best explained as an example: 2305.0994 is the same as 2305 994/10000.
What best Describes the number 5?
Common
Which reason best describes why you can divide any number by 100 by moving the decimal point two places to the left?
It is because the decimal system is a place value system and each step to the left represents a place value which is ten times as large.
Which Term Best Describes the number 0.5?
rational
What is the rule in changing fraction to desimal?
The first rule is to spell decimal correctly, otherwise you might get an answer to something else!There are three types of decimal numbers:(a) terminating.(b) recurring.(c) neither terminating nor recurring.The method, in each case is different.TERMINATINGCount the number of digits after (to the right of) the decimal point. Call this number D.The numerator of the fraction is the original decimal number written out without the decimal point. The denominator is 1 followed by D 0s. This fraction may need simplification.Example:23.456There are 3 digit [456] after the decimal point so D = 3 and so the denominator is 1000.So the fraction is 23456/1000 which can be simplified to 2932/125.RECURRINGCount the number of digits in the string that repeats. Call this number R.The numerator of the fraction is the original decimal number truncated (chopped off) after the first set of the repeating digits minus the original decimal number truncated before the repeating strings start. In both cases retain the decimal points. The denominator is the number formed by a string of R 9s ie 9, 99, 999 and so on. Again, the fraction may need simplification - it may first require multiplying numerator and denominator by a power of ten to get rid of the fractional part of the decimal.Example:17.35426426426....The recurring string is 3 digits long [426] so R = 3 and so the denominator = 999Numerator = 17354.26 - 17.35 = 17336.91The fraction is 17336.91/999 = 1733691/99900 which simplifies to 577897/33300.NEITHERThis is the decimal representation of an irrational number, not a rational number> Therefore, it cannot be expressed as a fraction. The best that you can do is to take the number formed by the first few digits and then treat it as a terminating decimal. This will give an approximate fraction.Examples:pi = 3.14159265359...Let approx pi = 3.1416Then following steps for a terminating fraction,fraction = 31416/10000 = 3927/1250If you had done approx pi = 3.14then you would have hadfraction = 314/100 = 157/50.
What best describes an even number?
It is a number which leaves no remainder when divided by 2.
Convert a fraction to a decimal number?
If you divide the numerator by the denominator, you will get the number as a decimal. Cherry.girl: In other words, If you have 1/2, grab a calculator and divide 1 by 2. You should get .5 for 1/2. Then that's it! ~Cherry.girl** commented Toni best if you don't have a calculator in reach 1/2 is equivalent =0.5
Can it be more practical to write a number in a decimal form?
In many cases, yes, one of the best examples being money. In decimal, everyone sees easily how much money this is: $1.25 The same unit of money in fraction is $1 1/4, which is pretty clumsy.
