Answer:
The simplified fractions are 1/4, 3/5, and 6/5.
Explanation:
To simplify fractions using the Greatest Common Factor (GCF), we find the largest number that divides evenly into both the numerator and the denominator. Let's simplify the fractions you mentioned:
For 32/128, the GCF is 32. Dividing both the numerator and denominator by 32 gives us 1/4.
For 51/85, the GCF is 17. Dividing both the numerator and denominator by 17 gives us 3/5.
For 42/35, the GCF is 7. Dividing both the numerator and denominator by 7 gives us 6/5.
So, the simplified fractions are 1/4, 3/5, and 6/5.
