The ratio of Mark’s pay per hour to Carl’s pay per hour is 3:4 given that Mark takes twice as long as to earn $6.00 as it takes Carl to earn $4.00. This can be obtained by dividing their hourly wages.
Given that, Mark takes twice as long as to earn $6.00 as it takes Carl to earn $4.00.
(Time taken for Mark to earn $6)=2×(Time taken for Carl to earn $4)
Time taken for Mark to earn $3 = Time taken for Carl to earn $4
This means that Mark takes the same amount of time to earn $3.00 as Carl earn $4.00.
Thus the ratio of Mark’s pay per hour to Carl’s pay per hour, 3/4 = 3:4
