Answer: 7/12
Step-by-step explanation:
From the question, we are told that Chelsea plays soccer 4/12 of the year and swims 3/12 of the year before taking a break from playing sports.
The fraction of the year that Chelsea spend participating in sports will be the addition of the fraction used for playing soccer and the fraction use for swimming. This will be:
= 4/12 + 3/12
= 7/12
This is just converting billion to million, vice-versa.
1 million = 0.001 billion
1,200 billion = 1,200,000,000,000
