Answer:

Reduced Fraction :

\frac{ - 63}{8}

Decimal : -7.875

Step-by-step explanation:

1. Put both fractions in improper form

\frac{( - 3 \times 2)  -  1}{2}  =  \frac{ - 7}{2}

\frac{4}{9}  =  \frac{4}{9}

2. Multiply -7/2 by the reciprocal of 4/9 to get answer

<em>Concept</em><em> </em><em>:</em><em> </em>

<em>\frac{ \frac{1}{5} }{ \frac{1}{3} }  = ( \frac{1}{5}  \times  \frac{3}{1} )</em>

<em>\frac{ - 7}{2}   \times  \frac{9}{4} =  \frac{ - 63}{8}</em>

Explain weather this equation is a linear equation <br> 4. y = 1 - x
sergey [27]

Answer:

Yes, it is a linear equation.

Step-by-step explanation:

<h2>Linear equation:</h2>

   An equation of the form ax + by +c = 0, where x and y are two variables and a, b,c are the non-zero real numbers is called a linear equation and the degree of the equation is 1.

       y = 1 - x

x + y - 1 = 0

Where a = 1 ; b=1 and c = -1

So, y = 1 -x is a linear equation.
