A 120-centimeter-long board is cut into two pieces. One piece is 5 times as long as the other piece.
What is the length of the longer piece of the board? Enter the answer in the box.
the long piece of the board is 100 cm and the shorter board is 20. you can solve this by dividing 120 by 6 since u need to have a piece that is 5x a piece which is a total of 6 pieces. Then multiply that number by 5 and that is your longest board.
