First of all, you need to change all of them to lowest terms.
1/2=1/2 (the same)
5/10=1/2 (5 divided by 5& 10 divided by 5)
2/4=1/2 (2 divided by 2 & 4 divided by 2)
1/2+1/2+1/2= 1 1/2 (mixed numbers) or 3/2 (improper fraction)
So, the answer to your question is 1 1/2 or 3/2 .
Hope it helps.

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
Use longer division its really easy
To find the discriminant we use b^2 - 4ac
equation of 4x^2 - 3x + 3 = 0
a b c
-3^2 - 4 (4)(3) = -39
if b^2 - 4ac < 0, there are 2 complex roots or...no real roots...in this case imaginary.
