Question

2/7=9/14 3/8Х=6 3Х=2/9

Answer 1

2/7Х=9/14

х=9/14:2/7=9/14*7/2=9/2*1/2=9/4=2 1/4

х=2 1/4

3/8Х=6

х=6:3/8=6/1*8/3=2/1*8/1=16

х=16

3Х=2/9

х=2/9:3=2/9*1/3=2/27

х=2/27

Answer 2

Let's solve the equations step by step:

1. 2/7 = 9/14 To simplify this equation, you can cross-multiply: 2 * 14 = 7 * 9 28 = 63 This equation is not true, so there is no solution.

2. 3/8 * X = 6 To solve for X, multiply both sides of the equation by the reciprocal of 3/8, which is 8/3: (3/8) * (8/3) * X = 6 * (8/3) (1) * X = 16 X = 16

3. 3X = 2/9 To solve for X, divide both sides of the equation by 3: 3X / 3 = (2/9) / 3 X = (2/9) / 3

   To divide by a fraction, you can multiply by its reciprocal: X = (2/9) * (1/3) X = 2/27

So, the solutions are:

1. The first equation has no solution.
2. X = 16 in the second equation.
3. X = 2/27 in the third equation.
