2 5/12 as a Repeating Decimal
What is 2 5/12?
2 5/12 is a mixed number, consisting of an integer part (2) and a fraction part (5/12). The fraction part can be simplified by dividing both the numerator and the denominator by their greatest common divisor, which is 1 in this case. Therefore, the simplified form of the fraction part is still 5/12.
Converting 2 5/12 to a Decimal
To convert 2 5/12 to a decimal, we need to convert the fraction part to a decimal and then add it to the integer part.
The fraction part, 5/12, can be converted to a decimal by dividing the numerator by the denominator:
5 ÷ 12 = 0.4166...
Since the decimal is repeating, we can write it in a shorter form using a bar:
0.416... = 0.4\bar{16}
Now, we add the integer part to the decimal part:
2 + 0.416... = 2.416...
Therefore, 2 5/12 as a repeating decimal is 2.416....
