To isolate the repeating component, multiply every facets through 10:
10x=four.Four‾10x = 4.Overlinefour10x=4.Four
Step 3: Subtract the Original Equation
Subtract the authentic equation from the new equation:
10x−x=four.4‾−0.Four‾10x – x = 4.Overlinefour – 0.Overlinefour10x−x=four.Four−0.Four
This simplifies to:
9x=49x = 49x=4
Step 4: Solve for x
Divide each sides with the aid of 9:
x=49x = frac49x=90 4
Thus, 0.4444444444444444444444444 as a fraction equals:
