The value of the given expression is -2357.953.
Given that, 0.9(3÷2.25− 1 8 (1 2 3 + 1 9 ))− 4 7 ÷0.8.
What is BODMAS rule?
The Bodmas rule follows the order of the BODMAS acronym ie B – Brackets, O – Order of powers or roots, D – Division, M – Multiplication A – Addition, and S – Subtraction. The BODMAS rule states that mathematical expressions with multiple operators need to be solved from left to right in the order of BODMAS.
Now, 0.9(3÷2.25− 1 8 (1 2 3 + 1 9 ))− 4 7 ÷0.8.
=0.9(3÷2.25− 1 8×142)− 4 7 ÷0.8.
=0.9(1.33− 1 8×142)− 4 7 ÷0.8.
=0.9×(-2554.67)-58.75=-2357.953
Hence, the value of the given expression is -2357.953.
