If the number is already in decimal form, you do not need to do anything to "convert" it to decimal!

How do you use a pattern to find the product of a power of 10 and a decimal?

If the power of ten is k, where k is an integer thenif k < 0 then the decimal point moves k places to the left;if k = 0 then the decimal point does not move; andif k > 0 then the decimal point moves k places to the right.


What is the process of changing a fraction to a decimal or to a percentage?

The answer depends on the form of the fraction. If it is a decimal fraction, you need to nothing to convert it to a decimal! (?). If it is in the form of a rational fraction, you need to use long division to divide the numerator by the denominator. The division will either come to an end or will go into a repeating loop of digits. The quotient from the division is the decimal equivalent. To convert to a percentage, simply move the decimal point two places to the right - inserting os if required.


How convert the binary number 110101001 to decimal then to octal?

You can use the Windows calculator to do the conversions. If you want to learn how to do it yourself:To convert binary to decimal, multiply the right-most digit with 1, the second digit (from the right) with 2, the third with 4, etc.To convert to octal, group the bits from the right to the left, in groups of 3. Convert each group to a decimal digit.


How do you convert a repeating decimal into percent?

you use the decimal that is repeating and out that number twice. examples: .6 repeating= 66 percent 0.9 repeating= 99%


Does an irrational number have to go on forever?

Yes. Any number with a decimal representation that terminates or repeats must be a rational number. If it terminates, it's obviously rational. For example, 0.12345 is clearly 12345/100000, and the same is true for any other decimal; simply multiply it by a power of ten large enough to convert it to an integer, and then for the fraction put that integer over that power of ten. Repeating is a little trickier; it may be best to illustrate with a couple of examples. Take the decimal 0.3333.... This multiplied by ten is 3.333...., and subtracting the original number obviously gives 3 exactly, so 10x - 1x = 9x = 3; x = 3/9 which reduces to 1/3. If it repeats in an alternating sequence (0.545454...) it's necessary to use a larger power of ten: 100x - 1x = 99x = 54; x = 54/99 = 6/11. One or the other of these can be done for any terminating or repeating decimal expansion, therefore they must be rational.

How do you convert Binary-to-Decimal and Decimal-to-Binary?

You can use a table to convert binary to decimal & back:MSBBinary DigitLSB2827262524232221202561286432168421Figure out the greatest power that will fit into the number you want to convert to binary. Move to the next lower power of two. If you can fit into the next lower number write down a "1", if it can't put down "0". Put together the binary answer.


How can you use place value to write a terminating decimal as a fraction with a power of ten in the deminator?

Finding a place value in a terminating decimal is easy. When placing the decimal always remember to place it at the tenth.

Why after the number 9 you have to put the numbers together?

Because we use the decimal system which has only ten symbols - for the numbers 0 to 9. In the decimal system, every time you get to a power of ten, the number starts one further place to the left.


What is the use of decimal points?

It separates the place values with positive power of ten from those with negative powers of ten. In other words, it separates the whole part of numbers from their fractional parts.

Convert to compatible units: convert horse-power to watts, and minutes to seconds. Then use the formula: work = power x time.


How do you convert the decimal 8.06 into a fraction?

Multiply by the smallest integral power of 10 to produce an integer from the original number, then use the resulting integer over the power of ten as a fraction. In this specific instance 8.06 X 100 = 806; therefore, the fraction is 806/100 = 403/50 or 8 and 3/50.

How do you turn a 3.9 into a fraction?

(1) Write the number without any decimal points. (2) Divide it by a power of ten. The power of ten that you use is the same as the number of digits after the decimal point in the original number. (3) Simplify the fraction by eliminating common factors (if any). Also, convert from vulgar to mixed fraction if required or desired. So here 3.9 = 39/10 and no further simplification is possible. In mixed fraction form this would be 3 9/10
