Question

7/X = 12/20 X/8 = 7/42

Answer 1

Пошаговое объяснение:

7/х = 12/20

12 * х = 20 * 7

12х = 140

х = 140 : 12

х = 140/12

х = 35/3

х = 11 2/3

х/8 = 7/42

х/8 = 1/6

6 * х = 1 * 8

6х = 8

х = 8 : 6

х = 8/6

х = 4/3

х = 1 1/3

Answer 2

To solve the equations 7/X = 12/20 and X/8 = 7/42, you can follow these steps:

1. Solve 7/X = 12/20:

   Cross-multiply to get rid of the fractions: 7 * 20 = 12 * X

   Simplify both sides of the equation: 140 = 12X

   Divide both sides by 12 to solve for X: X = 140 / 12 X = 35/3

2. Solve X/8 = 7/42:

   Cross-multiply to get rid of the fractions: X * 42 = 7 * 8

   Simplify both sides of the equation: 42X = 56

   Divide both sides by 42 to solve for X: X = 56 / 42 X = 4/3

So, the solutions to the equations are:

X = 35/3 and X = 4/3.
