Question 1000382
A roll of cloth is cut into pieces of equal lenght. The table Below shows the length of each piece and corresponding number of pieces that can be cut from the roll.
Table 
Length(m) 5. 8. 20. 
Number.   8. 5. 2.
-----
Comment: Notice that length * number is always 40 meters
------------------------

A) how many pieces of length 4m could be cut from this roll.
number = 40m/4m = 10 pieces
----------------------------------
B) if 80 pieces are cut from the roll what is the length of each piece
length = 40m/80 = 1/2 meter
