In general you can multiply through by the LCD

For example solve :-

2/x + 1 / (1+ x) = 11/12

The LCD is 12x(x + 1).

Now we multiply each term by 12x(x + 1)

2*12(x+1) + 12x = 11x(x + 1)

and this is solved in the usual way.

Answer:

The answer is "option b"

Step-by-step explanation:

Amount = $26,900

r= 0.0818 %

$i=\frac{r}{4}\\\\$

$=\frac{0.0818}{4}\\\\=0.02045$

t= 8 years

$n= 8 \times 4$

$=32$

$D=\frac{1-(1+i)^{-n}}{i}\\$

$=\frac{1-(1+0.02045)^{-32}}{0.02045}\\\\=\frac{1-(1.02045)^{-32}}{0.02045}\\\\=\frac{1-0.52319627}{0.02045}\\\\=\frac{0.47680373}{0.02045}\\\\=23.3155858$
