Выполните действия : 2 2/5×5/6-3/4×1 2/3 ( пж только не переводя в %) ​

Answer 1

2 2/5 · 5/6 - 3/4 · 1 2/3 = 3/4

1) 2 2/5 · 5/6 = 12/5 · 5/6 = 12/6 = 2

2) 3/4 · 1 2/3 = 3/4 · 5/3 = 5/4 = 1 1/4

3) 2 - 1 1/4 = 3/4

Ответ: 3/4.

Answer 2

Calculation:

To solve the given expression, let's break it down step by step:

1. 2 + 2/5 × 5/6 - 3/4 × 1 + 2/3

First, let's simplify the multiplication and division operations:

2 + (2/5) × (5/6) - (3/4) × 1 + (2/3)

2 + (2/5) × (5/6) - (3/4) + (2/3)

Next, let's calculate the multiplications and divisions:

2 + (1/3) - (3/4) + (2/3)

Now, let's find a common denominator for the fractions:

2 + (4/12) - (9/12) + (8/12)

Combine the fractions:

2 + (-5/12) + (8/12)

Finally, add the numbers:

2 + (3/12)

Simplify the fraction:

2 + (1/4)

Convert the mixed number to an improper fraction:

(8/4) + (1/4)

Add the fractions:

9/4

So, the result of the given expression is 9/4.
