Out of 1,200 students, 700 are boys. Therefore, the fraction would be 
.
To convert this into a percentage, divide 700 by 1,200.
= 0.583333 (or just 0.583 if you round)
Multiply 0.583 by 100 to get a percentage.
0.583 · 100 = 58.3
So, the percent of boys at the school is 58.3%.

We conclude that the sum of the first 8 terms of the arithmetic sequence is 17/5.
<h3>How to get the sum of the first 8 terms?</h3>
In an arithmetic sequence, the difference between any two consecutive terms is a constant.
Here we know that:
There are 7 times the common difference between these two values, so if d is the common difference:
Then the sum of the first 8 terms is given by:
So we conclude that the sum of the first 8 terms of the arithmetic sequence is 17/5.
