Reducing the fraction 9/12 would equal = 3/4
Because to reduce 9/12 we would need to know the least common denominator of both numbers.
In this case it's 3.
3 goes into 9, 3 times.
3 goes into 12, 4 times.
Which would then be 3/4.
We cannot reduce it any further because 3 is a prime number and doesn't go into 4.
Hope this helps,
