To multiply fractions you just multiply straight across for number 5 you would do 4 times 5 which equals 20 that wild be the top number of the fraction. Then 15 times 8 is 120 so that would be the the denominator in the fraction. So it would be 20/120. If you need to simplify the fraction it would be 1/6.
Answer:
$393.20
Step-by-step explanation:
There are two easy ways to solve this:
1) Use a setup and cross multiply.
First, set up your problem.
<u> $ x </u> = <u>40%</u>
$983 100%
$983 is the total amount, so it is equal to 100%. We're trying to find 40% of it, so we can label the amount as $x. Remember, each side has to be in the same type of measurements (i.e. dollars, percentages, inches, etc.).
Then, cross multiply. You should end up with:
100x = 39,320
Then, simplify.
x = 393.2
x = $393.20
2) Convert the percentage to a decimal and multiply.
First, convert the percentage you're looking for into a decimal:
40% × 100 = 0.4
Then, multiply the decimal with the total sales amount:
$983 × 0.4 = 393.2
= $393.20

Answer:
415,000
Step-by-step explanation:
First, find the decimal equivalent of 125%. To do this, divide 125 by 100 or move two decimal places to the right: 125/100 = 1.25
Now multiply the amount of cars sold last year, 332,000, by the percentage decimal, 1.25: 332,000 x 1.25 = 415,000
The car manufacturer sold 415,000 cars this year
