Rewrite both fractions with a common denominator:
8/11 x 5 = 40/55
3/5 x 11 = 33/55
40/55 is greater than 33/55 so 8/11 is greater than 3/5
Using the special angles sin 60° is also root 3 over 2
To awnser this , you first need to discover how much is 9% of 15000 that you invested.
To discover that you can just divide by 100 and multiply by 9
15000 ÷ 100 = 150
150 × 9 = 1350
So each year he earns $1350 but he has $1000 annual payments , so he only profit $350 a year.
Now to discover how long it will take to achieve $1.000.000 back you can just take the the $15.000 he needs to have 1.000.000 and divide by how much he profit each year
15000÷350= 42.85
which means it will take approximately 42 years and 10 months to achieve $1.000.000
