A unit fraction is a fraction where the numerator is 1 and the denominator is a positive integer

A unit fraction is a fraction where the numerator is 1 and the denominator is a positive integer. It can also be thought of as a fraction representing one part of a whole that has been divided into a specific number of equal parts.

For example, 1/2, 1/3, 1/4, and 1/5 are all examples of unit fractions. In these examples, the numerator is always 1, and the denominator represents the number of equal parts the whole is divided into.

Unit fractions are often used in mathematics to represent parts of a whole or to divide quantities into equal parts. They can also be used in operations such as addition, subtraction, multiplication, and division.

When adding or subtracting unit fractions, we need to have a common denominator. For example, to add 1/3 and 1/4, we need to find a common denominator, which in this case is 12. So, we can rewrite 1/3 as 4/12 and 1/4 as 3/12. Adding them together, we get 4/12 + 3/12 = 7/12.

When multiplying or dividing unit fractions, we simply multiply or divide the numerators and denominators. For example, to multiply 1/3 and 1/4, we can multiply the numerators (1 * 1) to get 1, and multiply the denominators (3 * 4) to get 12. So, 1/3 * 1/4 = 1/12.

To divide unit fractions, we can take the reciprocal (or flip) the second fraction and then multiply. For example, to divide 1/3 by 1/4, we can flip 1/4 to get 4/1, and then multiply: 1/3 ÷ 1/4 = 1/3 * 4/1 = 4/3.

In summary, a unit fraction is a fraction where the numerator is always 1 and the denominator represents the number of equal parts a whole is divided into. They can be used in various mathematical operations and can be added, subtracted, multiplied, or divided following specific rules and strategies.
