What am i supposed to write as answers on my work book?
Got my new first ever workbook from talk to me in Korean Level 1
There is 1 lesson subject i'm confused about. Could be also just because of my not 100% good English i just can't seem to understand. So here is 1 example.

𝓢𝓮𝓬𝓽𝓲𝓸𝓷 1 - 𝓥𝓸𝓬𝓪𝓫𝓾𝓵𝓪𝓻𝔂
𝘗𝘭𝘦𝘢𝘴𝘦 𝘥𝘦𝘧𝘪𝘯𝘦/𝘵𝘳𝘢𝘯𝘴𝘭𝘢𝘵𝘦 𝘦𝘢𝘤𝘩 𝘸𝘰𝘳𝘥 𝘪𝘯 𝘌𝘯𝘨𝘭𝘪𝘴𝘩. 𝘛𝘩𝘦𝘯 𝘸𝘳𝘪𝘵𝘦 𝘪𝘵 𝘪𝘯 𝘺𝘰𝘶𝘳 𝘱𝘳𝘦𝘧𝘦𝘳𝘳𝘦𝘥 𝘭𝘢𝘯𝘨𝘶𝘢𝘨𝘦.

2. 안녕 _________________
[an-nyeong]

3. 하세요 _________________
[ha-se-yo]

4. 안녕하세요 _________________
[an-nyeong-ha-se-yo]

5. 감사 _________________
[gam-sa]

6.합니다 _________________
[ham-ni-da]

7.감사합니다 _________________
[gam-sa-ham-mi-da]

I understand the translating full words meaning. But how do i translate/define the cut word? What am i supposed to do?

Answer

@Mariam~~미영 Thank you!! trying my best to understand but still little confused. But pretty sure just because of my English understading not so great. 
I understand the 안녕 means hello informally. So i just write ''Hello'' there?
and what am i supposed to write on the  하세요 part and why?

Answer

하다 is the verb 안녕 and 감사 are nouns 
안녕 means peace ( and it can be used alone as a shortcut to 안녕하세요  if you're talking to a friend  or someone younger than you ) so together 안녕 + 하다 = 안녕하다 the verb form of 안녕 and it means to be peaceful / calm / in a good health so 안녕하세요 means hello  ( literally be in a good condition  ) 하세요 is the imperative form of 하다

same thing with 감사합니다 , 감사 is the noun means gratitude , appreciation  하다 is the verb 
together 감사하다 means to be thankful 
and 감사합니다  is the verb conjugated and means I'm thankful  ( thank you )
