Reducing Fractions
Step 1:
Divide the numerator and the denominator by a common divisor.
Step 2:
Repeat until the only common divisor is 1.
Step 1:
2 is a common divisor of 16 and 24, so we can divide both numbers by 2.
16 24 ÷2 ÷2
Step 2: Repeat until the common
divisor is 1.
4 is a common divisor of 8 and 12, so we can divide
both numbers by 4.
8 12 ÷4 ÷4
2 3
