Answer 2

To solve the equation "3, (3): 2, 25 = 0, (4): x," we can follow these steps:

Step 1: Convert the repeating decimals to fractions.

• For 0,(4), let's call it "a." Multiply both sides by 10 to shift the decimal point to the right: 10a = 4,(4)

• Subtract "a" from both sides to eliminate the repeating part: 10a - a = 4,(4) - 0,(4) 9a = 4 a = 4/9

• Similarly, for 3, (3), let's call it "b." Multiply both sides by 10 to shift the decimal point to the right: 10b = 33,(3)

• Subtract "b" from both sides to eliminate the repeating part: 10b - b = 33,(3) - 3,(3) 9b = 30 b = 30/9 b = 10/3

Step 2: Substitute the fractions into the equation. 3, (3): 2, 25 = 0, (4): x 10/3: 2, 25 = 0, (4): x 10/3: 2, 25 = 4/9: x

Step 3: Solve for x. Cross-multiply to get rid of the denominators: (10/3) * x = (4/9) * (2, 25) 10x = 4 * (2, 25) 10x = 9

Divide both sides by 10: x = 9/10

Therefore, the solution to the equation "3, (3): 2, 25 = 0, (4): x" is x = 9/10.
