Question

Ramon is making book shelves. He bought a board that is 4/5 meter long. He needs 5 shelves. If he cuts 5 equal-sized pieces from the board, how long is each piece?​

Answer 1

Answer:

Each board is (4/25) meters long  = 0.16 meters long

Step-by-step explanation:

The board is 4/5 meters long, and he needs to cut 5 equal pieces, so we need to divide 4/5 of a meter in 5 parts.

This mathematically becomes: 4/5 divided by 5 which by the definition of division of rational numbers, is the same as :

4/5 times the reciprocal of 5 = (4/5) * (1/5) = (4/25) = 0.16 meters each board
