Answer the following questions.
(a) What is 95% of 80?
(b) 18 is what percent of 407
0

A. 76%

B. 7.2%

Step-by-step explanation:

80 x .0095=.76

18 x .0040=.072

move the decimal point over two digits and you have your answer

(a) 95% of 80 is basically you move the percent sign 2 places to the left which makes it 0.95 then just multiply 0.95x80

(b) the first step is to divide 18 by 40 to get the answer in decimal form:

18 / 40 = 0.4500

then, we multiplied the answer from the first step by one hundred to get the answer as a percentage:

0.4500 * 100 = 45.00%

we can prove that the answer is correct by taking 45.00 percent of 40 to get 18:

(40 x 45.00)/100 = 18

note that our calculator rounds the answers up to two decimals if necessary. Once again, the answer is as follows:

45.00%

{3 + i, 3 - i, 3, -1}
