A length if a rope is 8 meters long. How many 2/5 meter pieces can be cut from the length of rope

Since the rope is 8 meters long you will need to divide to find out how many 2/5 meter pieces can be cut from it.

So 8 divided by 2/5 will equal 20

Dividing is like multiplying

8 2 8 5

- - / - - - = - - - x - - -

1 5 1 2

8 times 5 = 40 and 1 times 2 = 2, so it is 40 over 2

which is also equal to 20

20 pieces can be cut.
