Numbers in decimal are expressed with a decimal point (.), for example, 0.38888888888. We are going to learn how to convert a decimal to a fraction.
The answer for 0.38888888888 as a fraction is approximately 35/90, which simplifies to 7/18.
Explanation
Converting a repeating decimal to a fraction involves recognizing the repeating part and using algebra to derive the fraction. You can follow the steps mentioned below to find the answer.
Step 1: Let x = 0.38888888888... The repeating part is 8.
Step 2: Multiply both sides by 10 to shift the decimal point: 10x = 3.8888888888...
Step 3: Subtract the original equation from this new equation to eliminate the repeating part: 10x - x = 3.8888888888... - 0.38888888888... which gives 9x = 3.5
Step 4: Solve for x by dividing both sides by 9: x = 3.5 / 9 = 35/90. Step 5: Simplify the fraction by dividing both the numerator and the denominator by their GCD, which is 5: 35/90 = 7/18.
