How do you calculate decimal expansion?
Theorem 1: If m be any rational number whose decimal expansion is terminating in nature, then m can be expressed in form of pq , where p and q are co-primes and the prime factorization of q is of the form 2x 5y 2 x 5 y , where x and y are non-negative integers.
What is the decimal expansion of 2 5?
0.4
Answer: 2/5 as a decimal is 0.4.
What is the decimal expansion for 1 3?
When expressing a rational number in the decimal form, it can be terminating or non-terminating but repeating and the digits can recur in a pattern. Example: 1/2= 0.5 is a terminating decimal number. 1/3 = 0.33333… is a non-terminating decimal number with the digit 3, repeating.
What is the decimal expansion of 1 by 7?
0.142857

What is the decimal expansion of 36 100?
0.36
Thus, 36/100 in decimal format is represented as 0.36.
What is 3 out of 5 as a decimal?
0.6
Answer: 3/5 as a decimal is 0.6.
What is 1/3 as a decimal rounded to 2 decimal places?
I ideally believe in significant figures, so I would rather write it down as 0.3 . Most people will write it down as 0.33,0.333,0.3333 , etc. In practice use 13 as 0.333 or 0.33 , depending on the level of accuracy required.
How can 1/3 be represented as a number?
To represent 1/3 on a number line, we divide the gap between O and A into 3 equal parts. Let T and Q be the points of division. Then, T represents 1/3 and Q represents 2/3, because 2/3 means 2 parts out of 3 equal parts as shown below. By using the same procedure, point O represents 0/3 and point A represents 3/3.
How to calculate the expansion of a decimal?
1 Split the decimal into its repeating parts: 0.121212… = 0.12 + 0.0012 + 0.000012… 2 Rewrite the parts from Step 1 as fractions: 3 Find the common ratio. Each of the above terms can be found by multiplying by the common ratio of 1/100:
How to find the decimal equivalent of a fraction?
In a fraction, the fraction bar means “divided by.”. So to find the decimal equivalent of a fraction like 1/4 you need to solve the math problem: 1 divided by 4. 1 ÷ 4 = 0.25.
How to turn a fraction into a division problem?
How to Turn a Fraction into a Division Problem. Dividing numbers is easy with a calculator. If you need to do long division by hand put the top number of the fraction (numerator) inside the division bracket and the bottom number (denominator) outside, to the left of the division bracket. The fraction 1 / 4 becomes 1 ÷ 4.
Where to put a fraction in a division bracket?
If you need to do long division by hand put the top number of the fraction (numerator) inside the division bracket and the bottom number (denominator) outside, to the left of the division bracket. The fraction 1 / 4 becomes 1 ÷ 4.
