Answer 1

Х:25/6=4/7:20/21
Х:25/6=3/5
Х=3/5×25/6
Х=1 2/3

Answer 2

Х:25/6=4/7:20/21
x*20/21=25/6*4/7
x*20/21=50/21
x=50/21:20/21              50/21:20/21=50/21*21/20=5/2
x=5/2
x=2 1/2

Answer 3

To find the value of x, we need to solve the equation:

X / (25/6) = (4/7) / (20/21)

To solve this, we can simplify the equation step by step:

Step 1: Convert the division of fractions to multiplication by the reciprocal: X / (25/6) = (4/7) * (21/20)

Step 2: Simplify the fractions: X / (25/6) = (3/7) * (21/5)

Step 3: Multiply the fractions: X / (25/6) = 63/35

Step 4: Invert the fraction on the right side and multiply: X = (63/35) * (25/6)

Step 5: Multiply the numerators and denominators: X = (63 * 25) / (35 * 6)

Step 6: Calculate the result: X = 1575 / 210

Step 7: Simplify the fraction, if possible: X = 7.5

So, the value of x is 7.5.
