Answer 1

8/5•(3/5+11/8)=1,6•(0,6+1,375)=3,16

Answer 2

Ответ:

Пошаговое объяснение:

3/5+11/8=24/40+1 15/40=1 39/40

8/5*1 39/40=8/5*79/40=79/25=3 4/25

Answer 3

To solve the expression, you need to follow the order of operations, which is usually remembered by the acronym PEMDAS:

1. Parentheses
2. Exponents
3. Multiplication and Division (from left to right)
4. Addition and Subtraction (from left to right)

Let's apply PEMDAS to the expression:

1. There are no parentheses or exponents in the expression.

2. We can perform the addition inside the parentheses: (3/5 + 11/8) = (24/40 + 55/40) = (24 + 55)/40 = 79/40

3. Now, we have a multiplication operation left: 8/5 × (79/40)

To multiply fractions, multiply the numerators together and multiply the denominators together:

(8/5) × (79/40) = (8 × 79) / (5 × 40) = 632 / 200

4. Finally, let's simplify the fraction: 632 divided by 200 equals 3.16

So, the final result is approximately 3.16.
