First you need to make them the say unit. I will convert the centimeters in the brochure to meters to match the table. To do this you need to divide 23 by 100 to get its meter value. that will get you .23 meters. Then divide the length of the table by how large each brochure is (1.5/.23) this will get you about 6.5. And since you can't have half a brochure on the table you will round down to 6 brochures on the table.

28 men are needed to paint the room in 3 hours
<h3><u>Solution:</u></h3>
Given that it takes 12 hours for 7 men to paint a room
We are asked to find number of men required to paint the room in 3 hours
Recognize, "paint the room" is 1 task. One job.
7 men -------- 12 hours ------ 1 job
(7/7) = 1 men ------- 12 x 7 (84) ------- same 1 job
The one men is rate is 84 hours to do the job
We can express this as 1/84 jobs per hour, the one-person rate
Now lets find how many men needed to paint the room in 3 hours
Let the required number of men for 3 hours be "a"
The rates of each person is simply additive.
corresponds to rate x hours = jobs and "a" is a variable for how many men
Thus 28 men are needed to paint the room in 3 hours
