It depends on the question, but if the questions is sort of like "Person A and Person B shared 40 sweets in the ratio 3:5, how many sweets did Person A get" then you add 3 and 5 to get 8, and then you do 40 ÷ 8 to get 5 which is 1 in terms of the ratio. Then, you would multiply 5 by 3 to get 15 sweets. If it's a different type of question then let me know so I can help out :)

What is the difference of the rational expressions below?

Stolb23 [73]

Answer: A

Step-by-step explanation:

We need to get the denominators to be same first before we can do anything to the numerator.

<em>The LCD (lowest common denominator) is </em> $3x^{3}$ <em>. To find the LCD, multiply the denominators together: </em> $x^{3}$ <em> · </em> $3x$ <em> = </em> $3x^{3$ .

Below, we are trying to get the denominators to equal the same or to $3x^{3}$ .

$\frac{3}{3} (\frac{4}{x^{3} } ) - \frac{x^{2} }{x^{2} } (\frac{2x-1}{3x} )$

$\frac{12}{3x^{3} } - \frac{2x^{3}-x^{2} }{3x^{3} }$

Now that the denominators are the same, we can subtract the numerators from each other.

$\frac{ 12 - (2x^{3} -x^{2})\\}{3x^{3} } \\$

$\frac{12-2x^{3} +x^{2} }{3x^{3} }$

Now, we can just reorganize the variables.

Answer: A or $\frac{-2x^{3} + x^{2}+12 }{3x^{3} }$
