What else can I help you with?
When you write a fraction in simplest form the numerator and denominator always or never have 1 as their only common factor?
Always
Is a fraction or a ratio by dividing the numerator and denominator by a common factor?
Dividing the numerator and denominator by a common factor is how you simplify a fraction.
How do we know the fraction is simplify?
When the GCF of the numerator and the denominator is 1.
What is a fraction called when the greatest common factor of the numerator and denominator is one?
The fraction is said to be in its simplest form
When the numerator and the denominator have only the number 1 as a common factor?
Yes. When the numerator and denominator have a GCF of 1, the fraction is in the simplest form. To simplify, find the GCF and divide both numerator and denominator by the same: Example: simplify 30/40 30/40 divided by 10/10 (1) = 3/4
Which fraction equals a repeating decimal?
If the denominator of the fraction in its lowest form, has any factor other than 2 or 5 then it will be a repeating decimal.
How are terminating decimals and repeating decimal reflected in fractions?
If a fraction, in its simplest form has a denominator whose only prime factors are 2 or 5, then the fraction is terminating. If the denominator has any other prime factor then the decimal is repeating.
How does 1 over 3 to 100th power have a repeating or terminating decimal representation?
It is repeating. Any fraction in simplest terms which has ANY prime factor other than 2 or 5 in its denominator will be a repeating fraction.
Which of the following fractions is also a repeating decimal?
Any fraction which, in its simplest form, has a denominator which has a factor other than 2 or 5.
Why is 411 a repeating decimal?
4/11 is a repeating decimal because, in its simplest from, the denominator of the rational fraction has a factor other than 2 or 5.
Is any factor of 3 or 9 as a denominator always to be a repeating decimal?
No. 36/9 = 4
Which fraction can be represented by a repeating decimal?
If the fraction, in its simplest rational form, has a denominator which has any prime factor other than 2 or 5, then proper representation of the fraction requires the use of repeating decimal.
What examples represents a repeating decimal?
Any rational fraction such that, in its simplest form, the denominator contains a prime factor other than 2 and 5 will be a repeating decimal.
How can you predict whether a quotient will be terminating decimal or a repeating decimal?
If the denominator of the fraction, when written in its simplest form, has any prime factor other than 2 or 5 then it will be a repeating decimal fraction otherwise it will terminate.
What can you predict whether a quotient will be a terminating decimal or repeating decimal?
If the denominator of the fraction, when written in its simplest form, has any prime factor other than 2 or 5 then it will be a repeating decimal fraction otherwise it will terminate.
How can you tell if a fraction repeats using the denominator's prime factors?
First reduce the fraction to its simplest form. If the denominator has any prime factor other than 2 or 5 then it is a repeating decimal. Otherwise it terminates.
What is the repeating decimal on a calculator?
It represents a rational fraction which, in its simplest form, has a denominator with a prime factor other than 2 or 5.
