Solve the problem. Make sure your answer is in simplest form. 3/16 x 4/21 = ?

Irina18 [472]

Answer:

$\frac{1}{28}$

Step-by-step explanation:

The result is given by means of some algebraic handling:

$\frac{3}{16}\times \frac{4}{21}$

$\frac{12}{336}$ - Multiplication of rationals.

$\frac{6}{168}$ - Dividing each term by 2.

$\frac{3}{84}$ - Dividing each term by 2.

$\frac{1}{28}$ - Dividing each term by 3.

After the fraction x plus 1 all over 2 minus the fraction x plus 2 all over 3 x have been combined using the least common denomi

RoseWind [281]

If I've read this correctly, it looks like this.

$\dfrac{(x + 1)}{2 - \dfrac{(x + 2)}{3x}}$

If that is correct, then the first step is to put the top part of the denominator over 3x

$\dfrac{(x + 1)}{\dfrac{6x - (x + 2)}{3x}} = \dfrac{(x + 1)}{\dfrac{5x -2}{3x}}$

The next part is to flip a three tier fraction. I'm afraid I have to show what happens. My latex is not that strong.

What you get is

$\dfrac{3x*(x + 1)}{(5x - 2)}$

This is just about your final answer. You could write it as

$\dfrac{3x^2 + 3x}{(5x - 2)}$

S = 46.24 - 33.75

S = 12.99
