How to divide the fifth grade
Reduction is the process of dividing the numerator and denominator by their common factor while keeping the value of the fraction unchanged
When the numerator and denominator are divided by their greatest common factor at the same time, the fraction obtained is the simplest fraction
24 / 36 = 12 / 18 = 4 / 6 = 2 / 3 this process is reductive, but 2 / 3 is the simplest fraction
