Final answer:
The first sentence is corrected to 'Jamie and Henry drank all of their orange juice.' and the second sentence to 'How many times have you been to the skating rink?'. The past tense 'drank' and possessive 'their' are used in the first, and 'been' is used to apply the present perfect tense in the second.
Step-by-step explanation:
To correct the given sentences:
- Jamie and Henry drank all of their orange juice.
- How many times have you been to the skating rink?
In the first corrected sentence, drinked is changed to drank, which is the past tense of drink, and there is corrected to their, which is the possessive pronoun. In the second sentence, went is corrected to been to properly use the present perfect tense with have.
