what is 10% of 661.77?

Answer 1

move the decimal one position to the left
10% of 10.00 is 1.00

Answer 2

10% = 0.1 0.1 x 661.77 = 66.177

for future reference:

The word "of" almost always means "multiplied by". Example: What is half of 20? Answer: one-half multiplied by 20, which is 10.

The word "per" almost always means "divided by". Example: I drove 300 miles in 5 hours. I went 60 miles per hour, because the number of miles divided by the number of hours is 60.

The symbol % means percent, which literally means "per hundred". I've already mentioned that "per" usually means divided by, and this is no exception. Percent means "divided by 100". Example: 60% means "60 divided by 100", or 3/5, or 0.6.

The word "what" or "what number" is a placeholder for a number. You can sometimes replace it with "x" to make an algebraic equation. Example: what multiplied by 3 equals 6. This means (x)(3)=6. Now you can solve for x by dividing both sides of the equation by 3. That gives you x=2.

Now, let's put these together. I will use the words "what", "of" and "percent" in a single sentence, then translate them for you.

Example: What is 50% of 30?

Translation: x = (50/100)(30)?

Simplification: x=15, which means 15 is 50% of 30.

Here's another one.

11 is what percent of 44?

Translation: 11 = (x/100) (44)

Simplification: 11/44 = x/100
1100/44 = x
25 = x, which means 11 is 25 percent of 44.

This may seem obvious, so it's a point that's often missed: The key to percentage questions as well as all word problems is accurately translating the question into an algebraic expression that you can solve. That requires that you clearly understand the meaning of simple words like "of", "per", "percent", and "what".

Answer 3

Ten percent is 10/100 of something. Since this number is in decimal notation, all you must do is shift the decimal place two to the left, and you will have the correct number. The answer is 6.6177.

Answer 4

66.17. are calculating the 10% off of a super calculater?

Answer 5

Move the decimal point one spot left.
66.177

Answer 6

move the decimal one place to the left making 66.177

Answer 7

100 : 661.77
then
10% : x
so X=661.77 x 10
and devide by 100
which is equal to 66.177

Answer 8

66.177 just move the decimal one place

Answer 9

half as much as 20% of 661.77

Answer 10

you just move the # of one decimal point so it would be 61.177
