Question

1 5/6:7 1/3=1,6:x и 7,6:x=2 1/9:2 4/9 Помогите пожалуйста:))

Answer 1

1 5/6:7 1/3=1,6:x
1 5/6:7 1/3 = 11/6 : 22/3 = 11/6*3/22 = 1/4 = 0,25
0,25 = 1,6:X
0,25*1,6 = X
X = 0,4


 7,6:x=2 1/9:2 4/9

2 1/9:2 4/9 = 19/9:22/9 = 19/9*9/22 = 19/22
7,6:X = 19/22
X = 19/22:7,6  = 19/22: 7 6/10 = 19/22:76/10 = 19/22*10/76 = 5/44

Answer 2

Calculation 1: 1 + 5/6 : 7 + 1/3

To solve this calculation, we need to follow the order of operations (PEMDAS/BODMAS). Let's break it down step by step:

1. Convert the mixed numbers to improper fractions: - 1 + 5/6 = (6/6) + 5/6 = 11/6 - 7 + 1/3 = (21/3) + 1/3 = 22/3

2. Perform the division: - (11/6) : (22/3) = (11/6) * (3/22) = 33/132 = 1/4

Therefore, the value of 1 + 5/6 : 7 + 1/3 is 1/4.

Calculation 2: 1,6 : x + 7,6 : x = 2 + 1/9 : 2 + 4/9

To solve this equation, we need to find the value of x that satisfies the equation. Let's break it down step by step:

1. Convert the mixed numbers to improper fractions: - 1,6 = 1 + 6/10 = 1 + 3/5 = 8/5 - 7,6 = 7 + 6/10 = 7 + 3/5 = 38/5 - 2 + 1/9 = 2 + 1/9 = 19/9 - 2 + 4/9 = 2 + 4/9 = 22/9

2. Rewrite the equation: - (8/5) : x + (38/5) : x = (19/9) : 2 + (22/9) : 2

3. Simplify the equation: - (8/5) : x + (38/5) : x = (19/9) : 2 + (22/9) : 2 - (8/5 + 38/5) : x = (19/9 + 22/9) : 2 - (46/5) : x = (41/9) : 2 - (46/5) : x = (41/9) * (1/2) - (46/5) : x = 41/18

4. Solve for x: - (46/5) : x = 41/18 - (46/5) * (18/41) = x - 828/205 = x

Therefore, the value of x that satisfies the equation 1,6 : x + 7,6 : x = 2 + 1/9 : 2 + 4/9 is 828/205.

I hope this helps! Let me know if you have any further questions.
