I agree with MSSUE on the first, but not on the second
LOL! I think bobpursley is right on both.
Number 1 is correct but I have to agree with bobpursley. Look at number two really closely and if you have to, use a calculator to help you!

To convert a percentage to a decimal, divide the percentage by 100.
For the first question, we have 0.45%. To convert it to a decimal, we divide 0.45 by 100:
0.45% ÷ 100 = 0.0045
So, the correct answer is c. 0.0045.
Now let's move on to the second question. To convert a percentage to a fraction, you can divide it by 100 and simplify if possible.
For the second question, we have 0.75%. To convert it to a fraction, we divide 0.75 by 100:
0.75% ÷ 100 = 0.0075
To simplify this fraction, we can see that 0.0075 is equal to 75/10000. Both the numerator (75) and denominator (10000) can be divided by 25 to simplify further:
75/10000 ÷ 25/25 = 3/400
So, the correct answer is b. 3/400.
