See if you find any common factors between 16 and 64. Then, divide both numbers by that common factor(s).
----------------------------------------------------------------------------------------
Do it in stages 16/64 is the same as 8/32 is the same as 4/16 is the same as 2/8 is the same as 1/4. (at each stage I divided the top and bottom number by 2).
Alternatively you could say that 4 sixteens makes 64 and divide the top and bottom by 16.
14 over 16 reduced to lowest terms is 7/8
It is: 4/7
27/8
16/300 = 4/75
26
17
Common factor is 7 so 13/16
16/11
2 and 3
16 over 24 in lowest terms is 2/3
Since the numerator of the fraction is prime, the proper fraction 13/16 cannot be reduced any further.
