How do I simplify rational expressions

Mathematics
1 answer:
ivolga24 [154]2 years ago
6 0

Answer:

a rational expression is an expression that has a RATIO in it

look at the word "RATIO"nal

a ratio is just a fraction...

so your question is "how to simplify fractions"

lots of approaches, this is one of them...

PRIME FACTOR the numerator and denominator

\frac{90}{135}

90 = 2 * 3 * 3 * 5

135 = 3 * 3 * 3 * 5

= 2/3 (the two 3's cancel and the 5's cancel)

Step-by-step explanation:

maw [93]

Answer:

y=15

(8,15)

Step-by-step explanation:

2y=30

Divide both sides by 2 to isolate y.

\frac{2y}{2} = \frac{30}{2}\\y=15

Because y=15, the solution is (8,15).

I hope this helps!

1/3x+2=3/4 how would I go about solving this???
Marizza181 [45]

Answer combine 1/2 and x.

X/2+2/3=1/6

Subtract 2/3 from both sides of the equation

X/2=1/6-2/3

Simplify the right side of the equation

-2/3 as a fraction with a common denominator, multiply by 2/2

X/2=1/6-2/3 x 2/2

Multiply 3 by 2

X/2 = 1/6 - 2/6 x 2

Combine the numerators over the common denominator

X/2 = 1-2 x2/ 6

Simplify the numerator

Multiply by -2 by 2

X/2 =1-4/6

Subtract 4 from 1

X/2= -3/6

Cancel the common factor of -3 and 6

Factor 3 out of -3

X/2 = 3(-1)/6

Cancel the common factor of 6

X/2 = 3 .-1/3.2

Rewrite the expression

X/2 = -1/2

Move the negative in front of the fraction

X/2= -1/2

Since both sides have the same Denominator the numerators must be equal.

X=-1
