This is a reduction to simplest form problem. You are given 33/36. All you need to do is to find a divisible number that can be divided to both the numerator and denominator, 33 and 36 respectively. It’s like finding the GCF or greatest common factor. The greatest common factor is the factor that divides both numbers. If you try to divide them by three, 33 divided by 3 gives 11 and 36 divided by 3 gives 12. The simplest form is 11/12.
