No.
9/13 is already as simplified as it is going to get because 13 is prime.
Yes, 918 can be simplified by factoring it into its prime components. The prime factorization of 918 is (2 \times 3^2 \times 7 \times 11). However, if you are looking for a simplified fraction, you need a specific context, such as a fraction that contains 918.
31/61 is a simplified fraction because 31 and 61 are both prime numbers.
No - since 11 is a prime number, the proper fraction 11/40 is as simplified as it can be.
23/60 and as 23 is a prime number the fraction can not be further simplified.
No, 19 is prime and if you ever have a prime number in a fraction, the fraction can not be further simplified (reduced).
Since the numerator of the fraction 19/36 is prime, the fraction cannot be simplified any further.
A fraction in which the numerator and denominator are co-prime.
Sometimes. 13 is a prime number. 13/26 can be simplified to 1/2. But 13/15 cannot be further simplified.
9/13 is already as simplified as it is going to get because 13 is prime.
79 is prime 79/100
Yes, 918 can be simplified by factoring it into its prime components. The prime factorization of 918 is (2 \times 3^2 \times 7 \times 11). However, if you are looking for a simplified fraction, you need a specific context, such as a fraction that contains 918.
31/61 is a simplified fraction because 31 and 61 are both prime numbers.
No - since 11 is a prime number, the proper fraction 11/40 is as simplified as it can be.
If the numerator of a fraction is a prime number, then the fraction cannot be simplified any further if the denominator is not a factor of the numerator. This is because a prime number has only two factors: 1 and itself. Therefore, the fraction is already in its simplest form.
If either of the numbers are prime, then the fraction cannot be further simplified. 5 is prime, therefore 5/42 is fully simplified.
23 is a prime number. It does not divide evenly into 70. For these two reasons, this fraction can not be simplified any further than 23/70.
