Answer: 17/18=34/36
11/12=33/36
Explanation:
17/18 and 11/12
First find the LCM, least common multiple, of the denominators 18 and 12.
In order to do that, list the factors of 18 and 12 and find the least common factors of them excluding 1.
18: 1, 2, 3, 6, 9, 18
12: 1, 2, 3, 4, 6, 12
Notice any common small factors? Yes they are 2 and 3. Now, multiply them with 18 and 12.
18*2=36
12*3=36
Hence, LCM is 36.
17/18=(17*2)/(18*2)=34/36
11/12=(11*3)/(12*3)=33/36
