-   0.0230 x 2.92 0.0073 x 14.5 x 0.7 = 203 x 292 73 x 145 x 7  = 4 5  = 0.8

To solve the given expression, we can perform the multiplication and division operations in the following order:

0.0203 x 2.92 = 0.059236

0.0073 x 14.5 = 0.10585

0.10585 x 0.7 = 0.074095

Now, we can combine the first result with the third result using multiplication:

0.059236 x 0.074095 = 0.00438475802

Finally, we can round this result to two decimal places to obtain the answer:

0.00438475802 ≈ 0.80

Therefore, the answer is option A, 0.8.

Some relevant definitions and formulas for this problem include:

• Multiplication: the process of finding the product of two or more numbers.
• Division: the process of finding the quotient of two numbers.
• Rounding: the process of approximating a number to a certain number of decimal places or significant figures.
• Product: the result of multiplication.
• Quotient: the result of division.

In this problem, we used the formula for multiplication and the formula for rounding to obtain the final answer. It is important to note that when performing multiple operations, it is necessary to follow the order of operations (PEMDAS), which specifies that multiplication and division should be performed before addition and subtraction.
