Let’s face it: fractions can be scary. Even though we encounter them in real life on a regular basis, they’re not something that comes naturally to most people. In the classroom, fractions often come up as part of math problems that involve ratios and decimals, which are also pretty difficult to understand and work with. If you just finished reading that last sentence and felt like throwing your book across the room out of frustration, you’re not alone! But fear not – we understand your pain, and we’re here to help!
What is a fraction?
A fraction is a part of something. It is written as a number divided by another number, with a line or slash between them. For example, to write the fraction 1/3, you would write the number one and a slash, then the number three on the other side. A fraction can be written in a few different ways. You may have seen fractions written with a denominator of 10 – for example, 1/10. You may also see fractions written with a denominator of 100 – for example, 1/100. There are also mixed fractions, which are fractions written with more than one number. The above example of 1/3 is a mixed fraction. The denominator is the number on the bottom of the fraction. The numerator is the number on the top of the fraction. The number on top of the fraction is the amount of the total, and the number on the bottom is the amount of what is remaining. For example, if you have 1/2 of a pizza and there are two people eating it, each person gets 1/2 of the pizza.
Fractions vs. Whole Numbers
Whole numbers, like one and two, are used to represent parts of a whole that do not have any fractional parts. For example, when you say that you have one slice of pizza, you are referring to the whole pizza with no fractional slices left over. However, fractions are used to represent parts of a whole with fractional parts left over. For example, if you say that you have three-quarters of a pizza, you are referring to the fractional part of the pizza that remains after everyone has had a whole slice.
How to add fractions with the same denominator
Let’s say you want to add 1/2 + 2/3. To find the sum, you first need to find the common denominator. The easiest way to do this is to convert both of the fractions to their simplest form. In this case, you would convert both fractions to their lowest terms. To convert to the lowest terms, find the largest number that divides evenly into both numbers of your fraction. Then, convert both numbers to the next lowest term. In this example, you would find that the largest number that divides evenly into both numbers is 2. Next, you would take 2 and convert it to the next lowest term, which is 1. Then, you would take both numbers and convert them to the next lowest term: 1/2 + 1/3 = 1/6 + 3/6 = 4/6. Next, you would add the numbers on the bottom: 4 + 3 = 7. Your final answer is 7/6.

How to add fractions with different denominators
Let’s say you have 1/2 + 3/7. In this example, you first need to find the least common multiple (LCM) of 2 and 7. The LCM of 2 and 7 is 21. Next, you would convert the fractions to their lowest terms. If you need help converting fractions to their lowest terms, follow the instructions in the above example. Once you have the two numbers in their lowest terms, you would add the numbers on the top: 1 + 3 = 4. Then, you would add the numbers on the bottom: 4 + 7 = 11. Your final answer is 11/21.
How to fix common mistakes when working with fractions
Let’s say you accidentally add a fraction that has the same denominator and you get the wrong answer. To fix this mistake, you have a few different options. First, you can simplify both of the fractions and add them again. To do this, follow the instructions in the above example. Alternatively, you can cross-multiply the two fractions to get the correct sum. To do this, multiply the denominators of both fractions. Then, multiply the numerators by the denominator of the first fraction, then multiply that number by the denominator of the other fraction. Next, add all of these numbers together. The last option is to multiply the two fractions together and then find the LCM of the two new numbers. Next, add the denominators of the new numbers and then add the numerators of the new numbers. Then, find the difference between the two numbers and you should have your final answer.
When adding fractions, make sure that you know what each fraction is representing. Also, it is important to understand the difference between numerators and denominators and keep the order of the fractions correct. Once you have the two fractions in their simplest form, add the numbers on top, and then add the numbers on the bottom. There are many different ways to add fractions, so you may need to try a few different methods to find the one that works best for you.
