A: 66/21 = 22/7 = 3 1/7
B: 60/20 = 3
C: 21/7 = 3
D: 45/15 = 3
E: 22/7 = 3 1/7

Answer:
Mike can stitch one shirt in 6 hours and in 1 hour he can stitch

= 6 hours
Now we calculate the work done in one hour.
He can stitch in 1 hour = shirts or 0.167 shirts
Mike can stitch one shirt in 6 hours and in 1 hour he can stitch shirts.
