Final answer:
To solve the math problem, follow the order of operations: multiply, add, subtract, and finally divide to get the answer of 3526.5.
Step-by-step explanation:
The subject of this question is Mathematics, specifically an arithmetic computation involving multiple operations – multiplication, addition, subtraction, and division. To solve the problem 90 times 78+ 53-20 Divided by 2, we follow the order of operations, also known as PEMDAS (Parentheses, Exponents, Multiplication and Division, Addition and Subtraction).
- Multiply 90 by 78 to get 7020.
- Add 53 to 7020 to get 7073.
- Subtract 20 from 7073 to get 7053.
- Finally, divide 7053 by 2 to get the final answer, which is 3526.5.
Therefore, the correct answer is 3526.5.
