Question

Y÷8,1=2 1/4÷6 3/4 решить

Answer 1

У : 8,1 = 2 1/4 : 6 3/4,
у : 8,1 = 9/4 : 27/4,
у : 8,1 = 9/4 * 4/27,
у : 8,1 = 1/3,
у = 1/3 * 8,1,
у = 1/3 * 81/10,
у = 27/10,
у = 2,7  (или  2 7/10)

Answer 2

To solve the expression, let's simplify each part step by step:

1. Y ÷ 8,1 = 2: This expression is not clear. If you meant "Y divided by 8.1 equals 2," we can solve it as follows: Y ÷ 8.1 = 2 Multiply both sides by 8.1 to isolate Y: Y = 2 × 8.1 Y = 16.2

2. 2 1/4 ÷ 6 3/4: To simplify this division, we can convert the mixed numbers to improper fractions: 2 1/4 = (2 × 4 + 1) / 4 = 9/4 6 3/4 = (6 × 4 + 3) / 4 = 27/4

Now, we can rewrite the expression as: (9/4) ÷ (27/4)

To divide fractions, we invert the divisor and multiply: (9/4) × (4/27)

The common factor of 4 cancels out, resulting in: 9/27

To simplify further, we can divide both the numerator and the denominator by their greatest common divisor, which is 9: 9/27 = (9 ÷ 9) / (27 ÷ 9) = 1/3

Therefore, 2 1/4 ÷ 6 3/4 simplifies to 1/3.
