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

1. I think the underlined number is 2. So It will be hundredths.
2. (8 x 100) + (6 x 10) + (3 x 1) + (1/10) + (4/100) + (1/1000)
Or 800 + 60 + 3 + 0.1 + 0.04 + 0.001
