Answer 1

$3.99

Ooo. A thumbs down for the correct answer. How does that work?

Answer 2

start by converting 10% to a fraction :

10% = 1/10

Then we have

10% of 39.99 = 1/10 x 39.99 = 1/10 x 39.99/1 = 39.99/10

Notice that 39.99 was rewritten as the fraction 39.99/1, and that to multiply two fractions together, you simply multiply the numerators and denominators.

Now we need to multiply the numerator and denominator of the fraction by 100 to get rid of the decimal :

39.99/10 = 39.99/10 x 100/100 = 3999/1000

The fraction 3999/1000 can now be converted to a decimal by carrying out the division by inspection, on paper or with a calculator :

3999/1000 = 3.999

So the final answer is

10% of 39.99 = 3999/1000 = 3.999
Method 2

Alternately, we can convert 10% directly to a decimal :

10% = 0.1

Then, doing the calculation by hand or with a calculator, we find

10% of 39.99 = 0.1 x 39.99 = 3.999

So the final answer is

10% of 39.99 = 3.999

Answer 3

find the amount when the base and percent are known.

amount = base x percent

Convert 10 % to decimal.

Remove the % symbol. divide 10 by 100

10/100 = 0.1

Multiply 39.99 times the decimal

39.99 x 0.1 = 3.999

The amount is $ 3.99 rounded to two decimal places.

$ 3.99 is 10% of $ 39.99

Answer 4

if you multiply 39.99 x .10, that would be equal to $3.999 because you always need to change the % to a decimal point.
For example:
84% of 45
.84 of 45
answer= 37.8

remember that OF means you multiply or times the number.

I hope i helped you in your problem.

Answer 5

Move the decimal point:

10% of $39.99 = $3.999 (rounded to $4.00)

Answer 6

Let ,10% of $39.99 be x
so,
(10/100) * 39.99 = x
(1/10) * 39.99 = x
so,
x=3.999
hence,
10% of $39.99 is $3.999

Answer 7

39.99*.10=3.999 however, when working with money we normally round to the nearest penny. In this case it would be 4.00.

Hope this helps!

Answer 8

to work out ten percent of something, you move the decimal point up one, which would make it $3.99.

therefore, 10% of $39.99 is $3.99

Answer 9

10%=0.1
0.1*39.99 = 3.999
39.99 - 3.999 = 35.991
therefor
10% 0f $39.99 is $35.99

Answer 10

It's half the amount if you stuck out for 20%
be twice the bargain


(I consider you need to learn what half and twice mean
before moving on to something really hard like what 10% means)

Answer 11

It would be $3.999, but with dollars and cents you would have to round it up to $4, if you can not have $3.999
