Answer: B) 1/4
The greatest common factor of 4 and 16 is 4. This is the largest factor that goes into both numerator and denominator
Divide the numerator and denominator by the GCF
4/4 = 1
16/4 = 4
This means 4/16 reduces to 1/4
Thinking in reverse, you can multiply top and bottom of 1/4 by 4 to get 4/16.
