Answer 2

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

               Given data:- $a=-1,b=8.$

               To find:- Value of above expression $\frac{b}{a} +9.$

               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 and b in the given equation we get,

            $\frac{b}{a} +9\\=>\frac{8}{-1}+9\\=>-8+9\\=>1$

    Hence we will get the value is $1.$
