In one workplace, 4 men performed 4 different jobs. Mr. Browne took 2 hours for his job, Mr. Johnson took 5 hours, Mr. Evelyn took 4 hours, and Mr. Fitt took 3 hours. What was the total number of man-hours used for the job?

14, or 4/14 if you're looking for the ratio.

Step-by-step explanation:

Simple addition, although maybe man-hours is some advanced concept and I'm wrong, in which case I'm sorry.

the difference between a number and 5 is -2.

step-by-step explanation:

notice that the equation you are given has -2 (negative 2) on the right side, not 2. when you subtract 5 from a number n, you are finding the difference between the number and 5.

the difference between a number and 5 is -2.
