Answer:
Both the numerator and the denominator of 21/24 can be divided by 3.
Explanation:
We will find the greatest common factor of both the numerator and the denominator.
21 = 3 x 7
24 = 3 x 2 x 2 x 2
We get the greatest common factor as 3.
When we divide 21 by 3, we get 7 (not divisible further or prime)
When we divide 24 by 3, we get 8.
Hence, Both the numerator and the denominator of 21/24 can be divided by 3.
