Answer:
21.25%
Step-by-step explanation:
To find the percent decrease, take the original amount and subtract the new amount
80-63 = 17
Divide this by the original amount
17/80 =.2125
Multiply by 100 to change to a percent
21.25%
1/4 of the population is A+
if you wanted 5/9 to have that blood type you would need to make an equation using 1/4 and 5/9.
5/9 x 1/4 = 5/36 or 0.139
You can verify because of all 9 had the A+ you can do the same equation but with 9/9 and 1/4
9/9 x 1/4 = 9/36 which is 0.25 or 1/4
Where P = perimeter, L = length, W = width, and A = area:
A = LW
P = 2(LW)
