There are three different situations, corresponding to the three types of decimal numbers: terminating, repeating and those which are neither terminating nor repeating. Whether the number is greater than or less than 40 makes no difference whatsoever.
Terminating: If the decimal number has d digits after the decimal point, then rename it as a fraction whose numerator is the decimal number without the decimal point, and the denominator is 10d or 1 followed by d zeros.
For example, 34.567
d = 3 so the denominator is 1000.
and the fraction is 34567/1000.
Repeating: Until you become expert at this I suggest you do this in two stages (using c and d separately). Suppose there are c digits after the decimal place where the digits are non-repeating, after which you get a repeating pattern of a string of d digits. Then the numerator is the old original string including one lot of the repeated digits minus the original string with none of the repeating digits. The denominator is 10c*(10d - 1), which is a string of d 9s followed by c 0s.
For example
123.26159159… There are 2 digits, "26", after the decimal point before the repeats kick in so c = 2, and the repeating string "159" is 3 digits long so d = 3.
So the numerator is 12326159 – 12326 = 12313833
and the denominator is 99900
Therefore the fraction is 12313833/99900.
Non-terminating and non-repeating: There is no way to get a proper fraction since, by definition, this is an irrational number. The best that you can do is to round it to a suitable number of digits and then treat that answer as a terminating decimal.
In all cases, you should check to see if the fraction can be simplified.
To convert a fraction to a decimal divide the numerator (top number) by the denominator (bottom number). To convert a percentage to a decimal divide it by 100. (A percentage is the numerator of a fraction with 100 as the denominator.)
To convert a fraction to a decimal, divide the top number by the bottom number.
They can show the same number, just in different ways. You can convert fractions into decimals or decimals into fractions.
It equals 1/3 because any whole number can be written as a fraction.
Write the whole number down. Convert the decimal into a fraction. Write the fraction next to the whole number and treat it as a mixed fraction. Thus: 4.1666..... Step I: 4 Step II: 0.1666... = 1/6 Step III: Answer = 41/6 You could convert 41/6 to 25/6 if you like.
To convert a fraction to a decimal divide the numerator (top number) by the denominator (bottom number). To convert a percentage to a decimal divide it by 100. (A percentage is the numerator of a fraction with 100 as the denominator.)
To convert a fraction to a decimal, divide the top number by the bottom number.
To convert a fraction to a decimal divide the numerator (top number) by the denominator (bottom number). To convert a decimal (or fraction) to a percentage multiply it by 100 %.
They can show the same number, just in different ways. You can convert fractions into decimals or decimals into fractions.
To convert a fraction to a decimal divide the top number (numerator) by the bottom number (denominator).To convert a decimal to a percentage, multiply it by 100eg 3/8 is :as a decimal: 3 ÷ 8 = 0.375as a percentage: 0.375 x 100 = 37.5 %
Multiplying by percentage is easy. All you have to do is convert the percentage into a fraction and then into a whole number.
Convert the mixed number to an improper fraction. For any fraction, divide the denominator into the numerator and multiply that total by 100. 3/4 = 0.75 = 75%
Converts a dollar price expressed as a decimal number into a dollar price expressed as fraction. For example, Dollar in Decimal Number is 1.25, Fraction is 32, the Dollar in Fraction will be 1.08.
It equals 1/3 because any whole number can be written as a fraction.
To find the percentage, convert the numbers into a fraction and then convert to percentage: 270 out of 538 = 270/538. Then divide the top number by the bottom number (270 ÷ 538 = .5018587) and move the decimal two places to the right to convert to percentage (.5018587 = 50.18587%).
Write the whole number down. Convert the decimal into a fraction. Write the fraction next to the whole number and treat it as a mixed fraction. Thus: 4.1666..... Step I: 4 Step II: 0.1666... = 1/6 Step III: Answer = 41/6 You could convert 41/6 to 25/6 if you like.
For a fraction, divide the numerator by the denominator and multiply by 100 for a percentage. If it's a mixed number, you first have to convert it to an improper fraction then do the same thing as for a fraction.
