Answer 2

Calculation 1: 15.96 / (9/25 + 2.04)

To solve this calculation, we need to follow the order of operations, which is often referred to as PEMDAS (Parentheses, Exponents, Multiplication and Division, and Addition and Subtraction).

1. First, we need to evaluate the expression inside the parentheses: 9/25 + 2.04. - The result of 9/25 is 0.36. - Adding 0.36 and 2.04 gives us 2.40.

2. Now, we can substitute the value of 2.40 back into the original expression: 15.96 / 2.40. - Dividing 15.96 by 2.40 gives us approximately 6.65.

Therefore, the result of the calculation 15.96 / (9/25 + 2.04) is approximately 6.65.

Calculation 2: 1 / (0.54 + 1.96)

Similar to the previous calculation, we need to follow the order of operations.

1. First, we need to evaluate the expression inside the parentheses: 0.54 + 1.96. - Adding 0.54 and 1.96 gives us 2.50.

2. Now, we can substitute the value of 2.50 back into the original expression: 1 / 2.50. - Dividing 1 by 2.50 gives us 0.40.

Therefore, the result of the calculation 1 / (0.54 + 1.96) is 0.40.

Please note that these calculations are approximate values based on the given numbers.
