You answer will be 6/8.

Because: 3/4=_/8

If you try to figure out how you got 4 to 8 you would divide 8 by 4 to get 2. Now you know to multiply 2 by both sides such as 3*2=6. SO your final answer will be 3/4=6/8

What’s 45 divided by 14.04

Vladimir79 [104]

Answer:

3.205

Step-by-step explanation:

convert the decimal number to a fraction

$45 \div \frac{351}{25}$

To divide by fraction, multiply by the reciprocal of that fraction

$45 \times \frac{25}{351}$

Reduce the numbers with the greatest common divisor 9

$5 \times \frac{25}{39}$

Calculate the product

$\frac{125}{39}$

Now turn it to a decimal which will be

$3.20513$

8/x-5 - 9/x-4 = 5/x^2-9x+20

_______________

Solve the equation:

$\mathsf{\dfrac{8}{x-5}-\dfrac{9}{x-4}=\dfrac{5}{x^2-9x+20}\qquad\qquad(x\ne 5~and~x\ne 4)}$

Reduce the fractions at the left side so that they have the same denominator:

$\mathsf{\dfrac{8(x-4)}{(x-5)(x-4)}-\dfrac{9(x-5)}{(x-4)(x-5)}=\dfrac{5}{x^2-9x+20}}\\\\\\
\mathsf{\dfrac{8x-32}{x^2-4x-5x+20}-\dfrac{9x-45}{x^2-4x-5x+20}=\dfrac{5}{x^2-9x+20}}\\\\\\
\mathsf{\dfrac{8x-32}{x^2-9x+20}-\dfrac{9x-45}{x^2-9x+20}=\dfrac{5}{x^2-9x+20}}\\\\\\
\mathsf{\dfrac{8x-32-(9x-45)}{x^2-9x+20}=\dfrac{5}{x^2-9x+20}}$

Numerators must be equal:

$\mathsf{8x-32-(9x-45)=5}\\\\
\mathsf{8x-32-9x+45=5}\\\\
\mathsf{8x-9x=5+32-45}\\\\
\mathsf{-x=-8}\\\\
\mathsf{x=8}\quad\longleftarrow\quad\textsf{this is the solution.}$

I hope this helps. =)
