Answer 1

Ответ:

1) 1 3/5 + 3 2/5 = 5

2) 7,5 • 3,8 =28,5

3) 17:5=3,4

4)28,5 - 3,4= 25,1

Answer 2

To solve this expression, you should follow the order of operations (PEMDAS/BODMAS), which stands for Parentheses/Brackets, Exponents/Orders (i.e., powers and square roots, etc.), Multiplication and Division (left-to-right), and Addition and Subtraction (left-to-right).

Let's break down your expression step by step:

1. Inside the parentheses: 1 3/5 + 3 2/5 = (8/5) + (17/5) = (8 + 17) / 5 = 25/5 = 5

2. Now, the expression becomes: 7.5 * 3.8 - 17 / 5

3. Next, perform the multiplication and division from left to right: 7.5 * 3.8 = 28.5 17 / 5 = 3.4

4. Now, subtract the result of the division from the result of the multiplication: 28.5 - 3.4 = 25.1

So, the value of the expression is 25.1.
