45% = .045
.005 = 0.5%
DCLXVI = 650
The Correct Answer is C
Let's evaluate each statement:
120% = 1.02:
To convert 120% to a decimal: 120%=1.20120\% = 1.20120%=1.20.
This statement is incorrect because 120% equals 1.20, not 1.02.
45% = 0.045:
To convert 45% to a decimal: 45%=0.4545\% = 0.4545%=0.45.
This statement is incorrect because 45% equals 0.45, not 0.045.
0.005 = 0.5%:
To convert 0.005 to a percentage: 0.005×100=0.5%0.005 \times 100 = 0.5\%0.005×100=0.5%.
This statement is correct.
DCLXVI = 650:
In Roman numerals: D = 500, C = 100, L = 50, X = 10, V = 5, I = 1.
Adding these: 500+100+50+10+5+1=666500 + 100 + 50 + 10 + 5 + 1 = 666500+100+50+10+5+1=666.
