The LCD is 3 * 5 * 5 = 75
So, 25/75, 45/75, 63/75, 65/75

L.C.D.=75

25/75=1/3
36/75=3/5
63/75=21/25
65/75=13/15

when you find the L.C.D., you multiply the highest denominater by 1, then 2, 3, 4, and so on. when you get the product, see if the rest of the denominaters can be divided by that number.

lcd=9*25=225
1/3=75/225 ,3/5=135/225,21/25=189/225,13/15= 195/225
