Q. Write the repeating decimal as a fraction..82828282
Denote Repeating Decimal: Let's denote the repeating decimal 0.82828282… by x.x=0.82828282…To convert this repeating decimal into a fraction, we can use algebra to create an equation that we can solve for x.
Multiply by 100: First, we multiply x by 100 to shift the decimal two places to the right, since the repeating pattern is two digits long.100x=82.828282...This step ensures that when we subtract x from 100x, the decimal parts will align and the repeating parts will cancel out.
Subtract to Eliminate Repeating Decimal: Now, we subtract the original x from 100x to get rid of the repeating decimal part.100x−x=82.828282...−0.82828282...99x=82We are left with a simple equation without the repeating decimal.
Solve for x: Next, we solve for x by dividing both sides of the equation by 99.x=9982This gives us the fraction form of the repeating decimal.
Check for Simplification: Finally, we check if the fraction can be simplified. However, since 82 and 99 have no common factors other than 1, the fraction is already in its simplest form.
