11/20
17/20
40 percent in fraction in lowest term = 2/5
The lowest term of 40 over 56 is 5/7
The lowest term of 35 over 40 = 7/8
7/40 is already in its lowest terms
The lowest common multiple of 8 and 20 is 40. 8 x 5 = 40 and 2 x 20 = 40.
If that is 9/20, it is already in its lowest term.
11/40 is in its lowest terms.
It is already in lowest terms.
The LCM is: 40
