The LCD is 3 * 5 * 5 = 75
So, 25/75, 45/75, 63/75, 65/75
Find L.C.D of the fractions and then express the fractions in terms of the L.C.D 1/3,3/5,21/25,13/15?
LCD is 75 i think
25/75, 45/75, 63/75, 65/75
Reply: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.
Reply:lcd=9*25=225
1/3=75/225 ,3/5=135/225,21/25=189/225,13/15= 195/225
