If you can subtract whole numbers, you can subtract fractions too!Ĭlick through the slideshow to learn how to subtract fractions. Subtracting fractions is a lot like regular subtraction. Solving subtraction problems with fractions Try solving some of the addition problems below. Just like in our earlier example, the denominator stays the same. In this example, the numerators are 7 and 2.ħ plus 2 equals 9, so we'll write that to the right of the numerators. Just like before, we're only going to add the numerators. Let's try another example: 7/10 plus 2/10. So you'll need 4/5 of a cup of oil total to make your cake. The denominators will stay the same, so we'll write 5 on the bottom of our new fraction.ģ/5 plus 1/5 equals 4/5. Make sure to line up the 4 with the numbers you just added. The numerators show the parts we need, so we'll add 3 and 1.ģ plus 1 equals 4. This is because we're finding how many parts we need total. Remember, when we add fractions, we don't add the denominators. Let's continue with our previous example and add these fractions: 3/5 of cup of oil and 1/5 of a cup of oil. If you can add whole numbers, you're ready to add fractions.Ĭlick through the slideshow to learn how to add fractions. Now that we know how to write addition problems with fractions, let's practice solving a few. Try setting up these addition and subtraction problems with fractions. Now that our example is set up, we're ready to subtract! This is because we want to subtract 1 part from 3 parts. Just like when we added, we'll stack our fractions to keep the numerators lined up. If you use 1/4 of a tank to drive home, how much will you have left? We can subtract these fractions to find out. Let's say you had 3/4 of a tank of gas when you got to work. We'll do the same thing to set up a subtraction example. This will make it easier to add them.Īnd that's all we have to do to set up an addition example with fractions. We can stack the fractions so the numerators are lined up. So we only need to add the numerators of our fractions. We just want to find out how many parts we need total. We don't want to change how many parts make a whole cup ( 5). That's because the bottom numbers, or denominators, show how many parts would make a whole. When you add fractions, you just add the top numbers, or numerators. To see how much oil you'll need total, you can add these fractions together. You also need 1/5 of a cup of oil to grease the pan. Let's imagine that a cake recipe tells you to add 3/5 of a cup of oil to the batter. For example, have you ever walked 1/2 of a mile to work and then walked another 1/2 mile back? Or drained 1/4 of a quart of gas from a gas tank that had 3/4 of a quart in it? You probably didn't think about it at the time, but these are examples of adding and subtracting fractions.Ĭlick through the slideshow to learn how to set up addition and subtraction problems with fractions. In real life, you might need to add or subtract fractions. Fractions show how much you have of something, like 1/2 of a tank of gas or 1/3 of a cup of water. In the previous lessons, you learned that a fraction is part of a whole. en/fractions/comparing-and-reducing-fractions/content/ Adding and subtracting fractions With Fraction Calculator Plus, your mobile phone or tablet is by your side in everyday life.Lesson 3: Adding and Subtracting Fractions Adding, subtracting, multiplying and dividing fractions has never been easier. NEW! Each result is also displayed as a decimal number. Each fraction is automatically scaled down to its simplest form to make it easier for you.
