I have 5 grades that = 18% of 100 each
I have 1 grade that = 10% of 100
giving total of 100%
How do I figure my average when I plug in my grades??

Convert 18% to decimal
Remove the % sign and divide by 100
18 / 100 = 0.18
100 x 0.18 = 18
Multiply 18 by 5 the number os su=tudents
18 x 5 = 90
90 + 10 = 100
The total students is 6
Divide 100 by 6 to get the total percent
100 / 6 = 16.66666667 %
The answer is 16.66 % rounded to two decimal places

(5 * 18) + (1 * 10)
now divide by 6
