a printer print 6 papers every 8 second running at the same rate ,how many papers does the printer print in 2 minutes

Ok first, there are (2x60) second = 180 second in 2 minutrs.

So you gave to find out FPB of 8 < 180.

180/8 = 22 left 2 second.

So you'll get 22x8 = 176 papers

But since there are 2 second left, then the machine seems still to print some papers. We can called it x.


Let's count x.

8/2 =6/x
8x = 12
X= 12/8
= 3/2

So the machine still has enough time to print 1 more paper.

So the final answer is 176 + 1 = 177 papers.

Good luck
