Omg. What grade are you in?
Answer: 20 children
Step-by-step explanation:
<u>Given</u>
Year 4: 11 cannot swim
Year 5: 21 can swim
Year 6: 18 of 30 can swim
Total 96 children
Total 37 cannot swim
<u>First Step: find the number of people from year 5 who cannot swim</u>
- There are 30-18=12 people who cannot swim in year 6
- There are 11 who cannot swim in year 4
- Thus, we use the total number [37]-[year 4+year 6]=37-23=14 people who cannot swim in the year 5
<u>Second Step: find the number of children in year 5</u>
- There are 21 children who can swim
- There are 14 children who cannot swim
- 21+14=35 children
<u>Third Step: find the number of children in year 4 who can swim</u>
- There are 30 children in year 6
- There are 35 children in year 5
- There are 11 children in year 4 who cannot swim
- There are in total 96 children
- 96-30-35-11=20 children in year 4 who can swim
Hope this helps!! :)
