Common Fraction Operations

When working with fractions on a calculator, it's important to understand the common operations involved. The following are the most common fraction operations and how to perform them on a calculator.

Addition and Subtraction

To add or subtract fractions, you need to find a common denominator. This is the number that both denominators can divide into evenly. Once you have a common denominator, you can add or subtract the numerators and simplify the result.

For example, if you want to add 1/4 and 3/8, you need to find a common denominator of 8. To do this, you can multiply the denominator of the first fraction (4) by 2 to get 8. Then, you can multiply the numerator of the first fraction (1) by 2 to get 2/8. Next, you can multiply the denominator of the second fraction (8) by 1 to get 8. Finally, you can multiply the numerator of the second fraction (3) by 1 to get 3/8. Now that both fractions have a denominator of 8, you can add the numerators to get 5/8.

Multiplication

To multiply fractions, you simply multiply the numerators together and the denominators together. The result is a new fraction that is the product of the two original fractions.

For example, if you want to multiply 2/3 and 1/4, you can multiply the numerators (2 and 1) to get 2, and multiply the denominators (3 and 4) to get 12. The result is 2/12, which can be simplified to 1/6.

Division

To divide fractions, you need to invert the second fraction (also known as the reciprocal) and then multiply the two fractions together. This is because division is the same as multiplying by the reciprocal.

For example, if you want to divide 2/3 by 1/4, you can invert the second fraction (1/4 becomes 4/1) and then multiply the two fractions together. This gives you 2/3 * 4/1, which simplifies to 8/3.
