I would like to know if both sentences below require the article "the" at the beginning of the sentence.
Sentence 1:
- Total number of cases in the US has increased by 2.2%.
- The total number of cases in the US has increased by 2.2%.
Sentence 2:
- Ratio of deaths to the number of cases in the US is 19 to 1.
- The ratio of deaths to the number of cases in the US is 19 to 1.
What rules of grammar do I need to consider while deciding if we need to use "the" or not with these sentences?
Clarification: These sentences are not used in headlines but in bullet points to communicate highlights of a day.
