First, divide 10 (amount of juice bottles) by 4 (amount of kids at red table) The answer should be 2.5, meaning each kid at the red table got 2 and a 1/2 bottles of juice.
next, multiply 6 (the amount of kids at the blue table) by 2.5 ( the amount of juice every kid should get). The answer should be 15.
So, there should be 15 bottles of juice given to the blue table.
The sentence is "The man drove away angrily" is in a passive voice, because it that sentence has a verb, that is making the verb stand out. Hope this helps:)
