Answer:
- The three pieces of equipment will be maintained on the same day again, 30 days from now.
- Os três equipamentos serão mantidos no mesmo dia novamente, daqui a 30 dias.
Explanation:
English Translation
In the kitchen of a restaurant, the stove is maintained every two days; that of the refrigerator, every three days; and the freezer, every five days. Today, the three pieces of equipment are being revised. How many days from now will this coincidence occur again?
Solution
The stove is maintained every 2 days.
The refrigerator is maintained every 3 days.
The freezer is maintained every 5 days.
If the three pieces of equipment are maintained today, on what day from now are they all going to be maintained in the same day?
The stove will be maintained on days 2, 4, 6, 8, 10, 12, 14, 16, 18, 20, 22, 24, 26, 28, 30, 32.... from now.
The refrigerator will be maintained on days 3, 6, 9, 12, 15, 18, 21, 24, 27, 30, 33... from now
The freezer will be maintained on days 5, 10, 15, 20, 25, 30, 35... from now.
The lowest common multiple for the three cases and the next time the three pieces of equipment will be maintained on the same day is evidently 30.
In Portugese/Em português
O fogão é mantido a cada 2 dias.
A geladeira é mantida a cada 3 dias.
O freezer é mantido a cada 5 dias.
Se as três peças de equipamento são mantidas hoje, em que dia a partir de agora elas serão mantidas no mesmo dia?
O fogão será mantido nos dias 2, 4, 6, 8, 10, 12, 14, 16, 18, 20, 22, 24, 26, 28, 30, 32 .... a partir de agora.
A geladeira será mantida nos dias 3, 6, 9, 12, 15, 18, 21, 24, 27, 30, 33 ... a partir de agora.
O freezer será mantido nos dias 5, 10, 15, 20, 25, 30, 35 ... a partir de agora.
O múltiplo comum mais baixo para os três casos e na próxima vez que as três peças de equipamento serão mantidas no mesmo dia é evidentemente 30.
