随你们怎么说英语

In English, you can say "It's up to you" or "It's your call" to mean "it's up to you to decide." For example, if someone asks you what you want to do and you want to leave the decision up to them, you can say "It's up to you" or "It's your call." It's a way of expressing that the decision is in their hands and that you are willing to go along with whatever they decide.
