To convert the repeating decimal 0.03703703703 into a fraction, we can employ mathematical techniques such as algebraic manipulation or use the concept of infinite geometric series. These methods provide systematic approaches to unraveling the fractional representation hidden within the repeating decimal pattern.
1. Algebraic Manipulation:
Algebraic manipulation involves treating the repeating segment of the decimal as a variable and employing basic arithmetic operations to isolate it and express it as a fraction. Let’s denote the repeating decimal as x=0.03703703703.
We begin by multiplying both sides of the equation by a suitable power of 10 to shift the repeating segment to the left of the decimal point. In this case, multiplying by 1000 is sufficient to eliminate the repeating part:
1000x=37.03703703
Next, we subtract the original equation from the multiplied equation to eliminate the repeating segment:
1000x−x=37.03703703−0.03703703703
Simplifying the equation:
999x=37
Finally, we solve for x to obtain the fractional representation:
x=37/ 999
2. Infinite Geometric Series:
Another method for converting repeating decimals into fractions involves leveraging the concept of infinite geometric series. In this approach, we express the repeating decimal as an infinite sum of a geometric sequence and then determine its sum using the formula for an infinite geometric series.
Let’s represent the repeating part of the decimal as a and the number of repeating digits as n. For 0.03703703703, we have:
a=0.037 , n=3
Now, the sum of an infinite geometric series is given by the formula:
Sum= a/1−r
Where a is the first term of the sequence and r is the common ratio between successive terms. Here, r is determined by shifting the decimal point of one place to the right, giving us r=0.001.
Substituting the values into the formula:
Sum = 0.037/ 1- 0.001 = 0.037/0.999 = 37/999
Thus, we arrive at the same fraction: 37/999
These methods provide systematic and reliable approaches for converting repeating decimals, such as 0.03703703703, into fractions, enabling a deeper understanding of the underlying mathematical principles involved.
