Question

3 9\14 : 2 1\7=x : 1,5

Answer 1

Ответ:

2,55

Пошаговое объяснение:

3 9/14 : 2 1/7 = х : 1,5

51/14 : 15/7 = х : 1,5

51/30 = х : 1,5

х = 1,5 * 51/30

х = 1,5 * 1,7

х = 2,55

Answer 2

To solve this proportion, we can cross-multiply:

(3 9/14) * 1.5 = x * (2 1/7)

First, we need to convert all the mixed numbers to improper fractions:

3 9/14 = (3 * 14 + 9) / 14 = 51/14

2 1/7 = (2 * 7 + 1) / 7 = 15/7

Now we can substitute these values into the equation and simplify:

(51/14) * 1.5 = x * (15/7)

76.5/14 = 15x/7

Cross-multiplying again:

76.5 * 7 = 14 * 15x

535.5 = 210x

Dividing both sides by 210:

x = 2.55

Therefore, the value of x is 2.55.
