I'd suggest you begin by subtracting 4 / (x-4) from both sides. Doing that would leave you with 1 / (x-4) - 2 / (x+2) = 0.

LCD is (x-4)(x+2). Mult. all three terms by (x-4)(x+2). The resulting equation is

x+2 - 2(x-4) = 0. Then x+2 = 2x - 8 => x = 10

Subst. 10 for x in the original equation to verify that 10 is indeed a solution.

By what percent will the fraction change if its numerator is increased by 25% and its denominator is increased by 20%? please an

d1i1m1o1n [39]

<h2>Answer:</h2><h2>The new fraction will chnage by 1.25 : 1.2 ratio, (i.e) = 1.04 %</h2>

Step-by-step explanation:

Let the fraction be represented as $\frac{x}{y}$ where x is the numerator and y is the denominator

Given that numerator will increase by 25 %, = 25% x

= 0.25 x

Given that denominator will increase by 20 %, = 20% y

= 0.2 y

The new fraction becomes = $\frac{x + 0.25 x}{y + 0.2 y}$

= $\frac{1.25 x}{1.2 y}$

= $(\frac{1.25}{1.2} ) \frac{x}{y}$

The new fraction will chnage by 1.25 : 1.2 ratio, (i.e) = 1.04 %
