Question

If a=-2, b=3, c=-1
Find the value of:-
(a) a/b + b/c - c/a​

Answer 1

• We have to evaluate the above expression by using the given data.

              Given data:- $a=-2,b=3,c=-1.$

              To find:-  $\frac{a}{b} +\frac{b}{c} -\frac{c}{a} .$

              Solution:-

• To solve the above equation we will follow the BODMAS rule.

• BODMAS is an order of mathematic operations.

• BODMAS rule is to be followed while solving expressions in mathematics. It stands for,

          B= bracket

           O= order of power or rules

           D= division

           M= multiplication

           A= addition

           S= subtraction

  Now put the value a,b, and c in the given equation we get,

         $\frac{a}{b} +\frac{b}{c} -\frac{c}{a} \\=>\frac{-2}{3} +\frac{3}{-1} -\frac{-1}{-2}\\=>\frac{-11}{3}-\frac{-1}{-2}\\=> -\frac{25}{6} \\=>-4.166.$

    Hence we will get the value is $-\frac{25}{6}$ or $-4.166.$

Answer 2

Given: $a=-2, b=3, c=-1$

We have to find the value of$a/b + b/c - c/a$.

As we know that the values of$a, b,\ and\ c$ are given that is$a=-2, b=3, c=-1$

By putting these values in the above equation, we are solving the above equation.

We are solving in the following way:

We have,

$a=-2, b=3, c=-1$

$a/b + b/c - c/a$

$=>\frac{-2}{3} +\frac{3}{-1} -\frac{-1}{-2} \\\\=>\frac{-2}{3} -\frac{3}{1} -\frac{1}{2} \\\\=>-\frac{25}{6}$

Hence, the solution of the above equation is$-\frac{25}{6}$.
