If you want to easily find the solution you can use your calculator.
Just divide 77 by 110 and see the result.
77/110 = 0.7 = 7/10 = 70/100 = 70%
100% - 70% = 30%
Explanation
110*x=77
x=77/110, but the answer is not a percent
So 77/110 = ?/100 => ?=77*100/110=70 => 70%
But since 70% does not represent a percentage decreasement, we need to subtract it from the 100%
100% - 70% = 30%
I don’t know but I need to answer a question so this is my answer
17.154 < 17.15 is incorrect.
17.15 is 17.150 which is less than 17.154 not greater than.
It means an exponment that what that means
Subtract 2.2 from 7 and that will be equal to w
