Answer 2

Ответ:

x=16/3

Пошаговое объяснение:

12:4/5х =20:1/4

12*5/4х =20:1/4

12*5/4х =20*4

3*5х =20*4

3*5х =80

15х =80

x=16/3

Answer 3

To solve the equation 12 : (4/5)x = 20 : (1/4), we can simplify both sides by multiplying each term by the respective denominators to eliminate the fractions.

On the left side, we have:

12 : (4/5)x = 12 * 5/4 * x = 15x

And on the right side, we have:

20 : (1/4) = 20 * 4/1 = 80

So the equation simplifies to:

15x = 80

To solve for x, we divide both sides of the equation by 15:

15x/15 = 80/15

x = 80/15

The value of x is approximately 5.33.
