Explain why the fraction 25 36 cannot be simplified.

Given fraction is 25 36 For simplification of a fraction, we divide both the numerator and denominator with their highest common factor. Example, 15 21 = 15 ÷ 3 21 ÷ 3 = 5 7 Now, factors of 25 are 1 , 5 , 25 . factors of 36 are 1 , 2 , 3 , 4 , 6 , 9 , 12 , 18 , 36 . So, for 25 36 , both the numerator and denominators have only one common factor as 1 i.e., they are co-prime numbers. Hence, the fraction cannot be further simplified.
