Write the percent as a decimal and as a fraction.

215%
a. 2.15; 2 1/20
b. 2.15; 2 3/20
c. 21.5; 21,1/2
d. 21.5; 21, 3/10

The given percent above is 215%. To convert this into decimal, let us divide this by 100. 215 / 100 and we get 2.15. So the decimal form of 215% is 2.15. Next, convert it into a fraction. Given the decimal form of 2.15, this is already equivalent to 2 15/100. To simplify this, since both 15 and 100 are divisible by 5, we get 3/20. Therefore, the fraction is 2 3/20. So the correct answer is option B. 2.15; 2 3/20.

the answer would be c ≈ 18.852*3.14= 6.286.28*3=18.85
