Answer 2

Answer:

Step-by-step explanation:

Concept:

The concept of basic mathematical formula will be used to solve the questions and also BODMAS rules will be used also.

Given:

A expression is given to solve that is $120\div[18- \{20-3(9-5)\}]$

To find:

We have to find the value of this expression.

Solution:

To solve this expression we have to work of brackets first.

$(9-5)$ is in first backet.the value after substraction is $4$ .

Then $3$ will be multiplied with $4$ .The answer is $12$ .

$\{20-12\}$ is in second bracket. The value after substraction will be $8$ .

Now , in third bracket the expression is $[18-8]$ . So the answer is $10$ .

Atlast $120$ will be divided by $10$ .

The final answer is $\frac{120}{10} =12$
