Question

118. 1) 3,5 : * :* = 2 : 0,4; 3): 4,4 = 6:12; 2) 0,56 4) 9,63 80 = * : 1000; * = 4,5 : 0,15.​

Answer 1

Пошаговое объяснение:

1)

3,5 : х = 2 : 0,4

3,5 : х = 5

х = 3,5 : 5

х = 0,7

2)

х : 4,4 = 6 : 12

х : 4,4 = 0,5

х = 0,5 * 4,4

х = 2,2

Answer 2

It seems like you've provided a series of equations with missing values. I'll do my best to solve them based on the given information:

1. 3,5 : * : * = 2 : 0,4; 3)

Let's try to fill in the missing values with variables. We have:

3,5 : x : y = 2 : 0,4

This can be written as:

3,5 / x = 2 / 0,4

Now, solve for x:

3,5 / x = 2 / 0,4

x = (3,5 * 0,4) / 2 x = 0,7

Now, we have x = 0,7. Let's proceed with the next part:

2. 0,56 4) 9,63 80 = * : 1000

Let's fill in the missing values with variables again:

0,56 / x = 9,63 / 80

Now, solve for x:

0,56 / x = 9,63 / 80

x = (0,56 * 80) / 9,63 x ≈ 4.64 (rounded to two decimal places)

So, x is approximately 4.64.

3. • = 4,5 : 0,15

Simply calculate:

• = 4,5 / 0,15
• = 30

So, the missing value in this equation is * = 30.
