Jessie works in a factory which makes chairs. He was given an order to make a number of chairs for a company. He made 1/7 of the number of chairs on first day, 3/8 of the number of chairs on second day and 1/5 of the number of chairs on the third day. If he needed to make 158 chairs on the fourth day to complete the order, how many chairs were ordered to be made? please help me​
