No, it is already a fraction in its lowest terms.
The fraction 291 over 485 in lowest terms is 3/5
The fraction is not reduced to lowest terms. We can reduce this fraction to lowest terms by dividing both the numerator and denominator by 4, because 4 is the Greatest Common Divisor of the numbers 52 and 64. So, this fraction reduced to lowest terms is 13/16
1/10
It is: 7/8 plus 5/8 = 12/8 or 3/2 in its lowest terms
It is not possible to reduce a percent to it's lowest terms. It is possible to reduce a fraction to it's lowest terms, however.
