Sure, I can help you with that! Fractions can seem a bit tricky at first, but with a step-by-step approach, you'll be able to add, subtract, multiply, and divide them with ease. Let's start with the basics.
What is a fraction?
A fraction represents a part of a whole. It is a way of expressing one quantity relative to another. Fractions consists of two parts: the numerator and the denominator. The numerator represents the top part of the fraction, which tells you how many parts you have. The denominator represents the bottom part of the fraction, which tells you how many equal parts the whole is divided into.
Adding and Subtracting Fractions:
To add or subtract fractions, the denominators must be the same. If they are not the same, you'll need to find a common denominator by finding the least common multiple (LCM) of the denominators. Once you have the common denominator, you can add or subtract the numerators while keeping the denominator the same.
Example:
Let's say we want to add 1/4 and 2/5:
Step 1: Find the common denominator.
The LCM of 4 and 5 is 20, so we can use 20 as the common denominator.
Step 2: Convert the fractions to have a common denominator.
1/4 = (1 * 5) / (4 * 5) = 5/20
2/5 = (2 * 4) / (5 * 4) = 8/20
Step 3: Add the fractions.
5/20 + 8/20 = (5 + 8) / 20 = 13/20
Multiplying and Dividing Fractions:
To multiply fractions, multiply the numerators together and multiply the denominators together.
To divide fractions, multiply the first fraction by the reciprocal of the second fraction (flip the second fraction and then multiply).
Example:
Let's say we want to multiply 2/3 and 3/4:
(2/3) * (3/4) = (2 * 3) / (3 * 4) = 6/12
Simplify the fraction: 6/12 = 1/2
Remember, it's always a good idea to simplify fractions whenever possible by dividing both the numerator and denominator by their greatest common factor.
I hope this explanation helps! If you have any more specific questions or need further clarification, feel free to ask.
