27-3×3+2×9÷6

27-3×3+2×1.5

27-9+3

27-12

15

We have to follow BODMAS Rule here.

Answer 2

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

            Given data:- $27-3\times(7-4)+2\times9\div(4+2).$

            To find:- Value of above expression.

            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

      Therefore,

      $\begin{array}{l}=27-3\times(7-4)+2\times9 /(4+2) \\=27-3\times(3)+2\times 9 /(4+2) \\=27-3\times3+2\times 9 /(4+2) \\=27-3\times3+2\times9 /(6) \\=27-33+2\times9 / 6 \\=27-9+2\times 9 / 6 \\=27-9+18 / 6 \\=27-9+3 \\=18+3 \\=21\end{array}$

    Hence we will get the value is $21.$
