The answer depends on the value of l in 5l.
21/40 cannot be reduced.
21/40 cannot be reduced.
The fraction 13/40 cannot be reduced any more.
The reduced fraction for 40 over 64 is 5/8
The reduced fraction for 40 over 100 is 2/5
189 and 40 have no factor in common and so the fraction cannot be reduced.
19/40 is in the reduced form as there is no whole number that divides 19 and 40 evenly (remainder zero).
it can be reduced to 4 over 3
No.
no 3 does not go (evenly) into 40
