## What is Fractions?

Fractions are the building blocks of mathematics. They are a way of expressing a number or amount that is not an integeror whole numberbut instead is part of a larger whole. Fractions can be used to represent parts of a whole, such as one-half, one-quarter and three-fourths. They are also used to represent ratios, such as two-thirds, which indicate that there are two parts out of three total parts. Learning fractions can help students understand more complex operations involving fractions and decimals. For example, students who understand how to add and subtract fractions will be more prepared for learning how to multiply them.Fractions can be written in many forms: improper fraction (e.g., 7/4), mixed numbers (e.g., 1 2/3), or decimals (e.g., 1.75). To add or subtract fractions with different denominators, the first step is finding the least common denominator (LCD). This is the lowest multiple shared by both denominators; if one fraction has 2 as its denominator and another has 4 as its denominator; then 8 would be their LCD since it’s the lowest multiple shared by both numbers that isn’t itself a fractional number like 5/4 or 3/2). Once you have found the LCD, you convert each fraction into an equivalent fraction with that same LCD before adding or subtracting them together. Multiplying and dividing fractions can also come in handy when dealing with more complex problems involving decimals or proportions. To multiply two fractions together, you simply multiply their numerators together and their denominators together; this results in your final answer being expressed in terms of another single fraction rather than having remainders like when dealing with decimal multiplication. Similarly for division problems involving fractions, you just flip the second fraction over (known as inverting), then proceed to multiply it against your original value just like before. Overall understanding how to work with fractions is an essential skill for success in math at every level from elementary school all through college level courses such as Calculus. It helps individuals better comprehend ratios & proportions which have many real life applications from cooking recipes & measuring ingredients all the way up to business calculations & finance decisions.
