1. Let’s find how many parts are produced in 1 hour on the first machine.
728: 7 = 104 (details).
2. Let’s find how many parts are produced on the second machine, if it is known that there are 235 more parts than on the first machine.
728 + 235 = 963 (details).
3. Let’s find how many parts are produced in 1 hour on the second machine.
963: 9 = 107 (parts).
