When we talk about fractions, we are usually referring to a part of a whole, such as 1/2 or 3/4. A fraction is made up of two numbers: a numerator and a denominator. The numerator is the number on top of the fraction and the denominator is the number on the bottom of the fraction. In the fraction 1/2, for example, 1 is the numerator and 2 is the denominator.
What is 2.9 as a Fraction?
2.9 as a fraction is 2 9/100. In other words, it is two and nine-hundredths. When we convert a decimal like 2.9 to a fraction, we place the decimal point in between the 2 and the 9, and then count how many digits there are to the right of the decimal point. In this case, there are two digits. So, we put a 2 over a hundred (10^2). The final answer is 2/100, or 2%.
Decimal to Fraction
2.9 as a fraction is 29/10. To convert 2.9 to a fraction, divide 2.9 by 1 and then simplify the resulting fraction.
Fraction to Decimal
Converting a decimal to a fraction is a three-step process. The first step is to determine if the decimal is a terminating or repeating decimal. A terminating decimal is one where the digits after the decimal point all stop, such as 0.5, 0.75, 1.25 and so forth. A repeating decimal, on the other hand, has digits that go on forever after the decimal point, such as 0.33 or 1.66. You can tell if a decimal is repeating by seeing if any digit after the decimal point repeats itself over and over in a pattern. For example, in 0.333333333…, the “3” repeats itself indefinitely. In 1/3, on the other hand, there is no number that repeats indefinitely after the decimal point (although 1/3 = 0.333333333…).
To convert a terminating decimal to a fraction, count the number of digits that are to the right of the decimal point and put that many zeroes after the one in your fraction (or write out as many zeroes as there are digits). So 0.5 would be written as 1/2 (one-half), and 1.25 would be written as 1/4 (one-quarter).
To convert a repeating decimal to a fraction, you have to use algebraic methods (multiply both sides of an equation by some number so that the pattern stops repeating). For example:
0.333333333… = 3/9 because 3 x 0.333333333… = 1
1/3 = 3/9 because 1 x 3/9 = 3/9
To sum it up, 2.9 as a fraction is 29/10. This can be reduced to 2 9/10 or even just 2 9, which is read as “two point nine.” When writing fractions, it is industry practice to put the fraction in subscript after the whole number, like so: 2.9 = 2 9/10.
