As per the problem
The chemicals in my swimming pool use a ratio of 5 tablets of chlorine for every 14 days.
we have been asked to find
Which ratio shows the number of chlorine tablets needed for 42 days?
Since for each 14 days the number of tablets required is 5
So if you multiply the number of days by some number then, we will have to multiply the number of tablets required by the same number.
So When number of days
Then the number of tablets required for 42 days is 
3.4, 13, 18.4, 44.3, 82.4, 49.3 :) hope this helped

If 25 students took an exam and 4 of the students that took the exam failed, what percent of the students passed?
To find out how many students passed, we can subtract 4 from 25 and we will get a difference of 21.
The fraction
represents the number of students who passed the exam out of all the students.
To find out what percent of the students passed, we can turn
into a percent.
21 ÷ 25 = 0.84
0.84 × 100 = 84%
Therefore, 84% of the students who took the exam passed.
