Find the phrasal verbs in the article. Are they separable or inseparable? How do you know?

The phrasal verbs in the article are:

• "come up with" (separable)
• "end up" (inseparable)
• "break it up" (separable)
• "clean it up" (separable)
• "work out" (separable)
• "throw away" (separable)
• "run out of" (separable)

I know "come up with" is separable because the object "it" can come before or after the particle "up". "End up" is inseparable because the object "in the oceans" cannot come between "end" and "up". "Break it up", "clean it up", "work out", "throw away", and "run out of" are separable because their objects can come before or after their particles.
