What is the fractional form of a decimal number?
It is a decimal number in which there is at least one non-zero digit after the decimal point (excluding an infinitely repeating 9s).
What type of decimal has a finite number of digits after decimal point?
A decimal of a fraction whose denominator is of the form 2ax5b where a and b are non-negative integers.
What is the scientific notation for 21500?
Scientific notation is a number with a non-zero digit before a decimal point multiplied by a power of 10: 21500 = 2.15 x 104
How can you identify recurring and non-recurring decimal number from rational form itself?
If the prime factorisation of the fraction's denominator consists only of the primes 2 and/or 5 it will be a non-recurring decimal; otherwise it will.
Can a non-terminating decimal be a non-repeating decimal?
Yes. Every irrational number has a non-terminating, non-repeating decimal representation.
What numbers are divisible by 104?
Every number is divisible by any non-zero number.Any element of the set of numbers of the form 104*k, where k is an integer, is evenly divisible.
Which statements are true for irrational numbers written in decimal form?
The decimal representation in infinite, non-recurring.
Is 9 over 7 a decimal fraction?
No. (Though you could express it in decimal form, as 1.285714285714..., a repeating non-terminating decimal.)
What is the fractional form of a decimal number?
It is a decimal number in which there is at least one non-zero digit after the decimal point (excluding an infinitely repeating 9s).
What type of decimal has a finite number of digits after decimal point?
A decimal of a fraction whose denominator is of the form 2ax5b where a and b are non-negative integers.
What is the scientific notation for 21500?
Scientific notation is a number with a non-zero digit before a decimal point multiplied by a power of 10: 21500 = 2.15 x 104
What does the fraction 1 over 3 equal in decimal form?
1/3 is a non termination decimal. It is .33333 repeating forever
What is non-repeating decimal?
A non-repeating decimal is a decimal that never repeats itself. For example, pi is a non-repeating decimal.
What relationship can you notice between the fractions and the decimal equivalent?
The decimal equivalent terminates if and only if the denominator (of the simplest form) is 2a5bfor some non-negative integers a and b. In all other cases the decimal form is recurring.
How can you identify recurring and non-recurring decimal number from rational form itself?
If the prime factorisation of the fraction's denominator consists only of the primes 2 and/or 5 it will be a non-recurring decimal; otherwise it will.
Can a non-terminating decimal be a non-repeating decimal?
Yes. Every irrational number has a non-terminating, non-repeating decimal representation.
What is non terminatin repeating decimal?
A terminating decimal is a rational number. A non-terminating, repeating decimal is a rational number. A non-terminating, non-repeating decimal is an irrational number.
