Получается 4,8. 
Надеюсь, понятно. А то я не мастер писать мышкой:)

Answer 2

To calculate the given expression, follow the order of operations (PEMDAS - Parentheses, Exponents, Multiplication and Division, Addition and Subtraction). Let's simplify the expression step by step:

Step 1: Simplify the expression within the parentheses: (3 3/8 * 4/9 + 9.54)

Step 2: Convert the mixed number to an improper fraction: 3 3/8 = (8 * 3 + 3) / 8 = 27 / 8

Step 3: Multiply the fractions: (27/8 * 4/9)

Step 4: Multiply the numerators and denominators: (27 * 4) / (8 * 9) = 108 / 72

Step 5: Simplify the fraction: 108 / 72 = 3 / 2

Step 6: Add the result to 9.54: 3/2 + 9.54 = 11.04

Now, we have the first part of the expression simplified to 11.04.

Next, we'll calculate the second part of the expression:

Step 1: Simplify the expression within the parentheses: (5.1 - 2.8)

Step 2: Perform the subtraction: 5.1 - 2.8 = 2.3

Now, we have the second part of the expression simplified to 2.3.

Finally, let's divide the results of the two parts:

11.04 / 2.3 ≈ 4.80

So, the final result of the expression (3 3/8 * 4/9 + 9.54) / (5.1 - 2.8) is approximately 4.80.
