reduction
Divide by the same number of denominators and numerator. Make it the smallest denominator.
The denominator may become 1 when you reduce. If the denominator is 1, use an integer.
Simplification is the process of dividing both the numerator and denominator by the same number to obtain the smallest possible denominator.
Reduce fractions by dividing both the numerator and denominator by their greatest common factor.
If reducing, the denominator may become 1. In such a case, it should be expressed as an integer.
Greatest common divisor
The greatest common divisor is the largest common factor of two numbers.
ex) The greatest common divisor of 12 and 16, for example.
12 → 1,2,3,4,6,12
16 → 1,2,4,8,16
The maximum common divisor of 12 and 16 is 4. So, the greatest common divisor is 4.
Let's find the greatest common factor and simplify.
