Q. Write the repeating decimal as a fraction..033033033
Identify Repeating Pattern: Identify the repeating pattern in the decimal. The repeating pattern is 033, which repeats indefinitely after the decimal point.
Express as Infinite Sum: Express the repeating decimal as an infinite sum of its repeating parts. Since the pattern 033 starts after the second decimal place, we can write it as:0.033033033...=0.033+0.00033+0.0000033+...
Convert to Fractions: Convert each term in the sum into a fraction. The first term is 100033, the second term is 10000033, and so on. This gives us:0.033033033…=100033+10000033+1000000033+…
Recognize Geometric Series: Recognize that the sum forms a geometric series with the first term a1=100033 and the common ratio r=1001.
Use Sum Formula: Use the formula for the sum of an infinite geometric series, which is a1/(1−r), to write the repeating decimal as a fraction. Substitute a1=100033 and r=1001 into the formula.Sum = (100033)/(1−1001)
Simplify Expression: Simplify the expression by finding a common denominator and performing the division.Sum = (100033)/(10099)Sum = (100033)⋅(99100)
Multiply Numerators and Denominators: Multiply the numerators and denominators to get the fraction.Sum = (33×100)/(1000×99)Sum = 3300/99000
Reduce to Simplest Form: Reduce the fraction to its simplest form by dividing both the numerator and the denominator by their greatest common divisor, which is 3300.Sum=990003300=301
