Calculation of Remaining Boards on the Warehouse

To calculate the number of boards remaining on the warehouse, we need to subtract the number of boards used for the construction of the shed and the number of boards used for the repair of the house from the initial number of boards on the warehouse.

Given: - Initial number of boards on the warehouse: 840 - One-sixth (1/6) of the boards were used for the construction of the shed. - One-seventh (1/7) of all the boards were used for the repair of the house.

Let's calculate the number of boards remaining on the warehouse step by step:

1. Calculate the number of boards used for the construction of the shed: - One-sixth (1/6) of 840 boards = 840/6 = 140 boards used for the construction of the shed.

2. Calculate the number of boards used for the repair of the house: - One-seventh (1/7) of 840 boards = 840/7 = 120 boards used for the repair of the house.

3. Calculate the number of boards remaining on the warehouse: - Initial number of boards on the warehouse - boards used for the construction of the shed - boards used for the repair of the house - 840 - 140 - 120 = 580 boards remaining on the warehouse.

Therefore, there are 580 boards remaining on the warehouse.
