Final answer:
To simplify each fraction, find the greatest common factor (GCF) of the numerator and denominator and divide them both by it.
Step-by-step explanation:
To write each fraction in simplest form, we need to find the greatest common factor (GCF) of the numerator and denominator and divide them both by it. Let's go through each fraction:
- For 9/18, the GCF of 9 and 18 is 9, so dividing both the numerator and denominator by 9 gives us 1/2.
- For 21/35, the GCF of 21 and 35 is 7, so dividing both the numerator and denominator by 7 gives us 3/5.
- For 36/48, the GCF of 36 and 48 is 12, so dividing both the numerator and denominator by 12 gives us 3/4.
