Article: To add fractions, they must have the same denominator. If they do, simply add the numerators together. For instance, to solve 5/9 + 1/9, just add 5 + 1, which equals 6. The answer, then, is 6/9 which can be reduced to 2/3. If you need to subtract fractions, they must have the same denominator, just like if you were adding them. All you have to do is subtract the smaller numerator from the larger numerator to solve the problem. For instance, to solve 6/8 - 2/8, all you do is take away 2 from 6. The answer is 4/8, which can be reduced to 1/2. to add or subtract fractions without the same denominator. If the fractions don't have the same denominator, you'll need to find a common multiple of both denominators and convert each fraction so they have the same denominator. To do this, multiply both the numerator and denominator by the number that will convert it to the common multiple. Then, add or subtract the numerators to find the answer.  For example, if you need to add 1/2 and 2/3, start by determining a common multiple. In this case, the common multiple is 6 since both 2 and 3 can be converted to 6. To turn 1/2 into a fraction with a denominator of 6, multiply both the numerator and denominator by 3: 1 x 3 = 3 and 2 x 3 = 6, so the new fraction is 3/6. To turn 2/3 into a fraction with a denominator of 6, multiply both the numerator and denominator by 2: 2 x 2 = 4 and 3 x 2 = 6, so the new fraction is 4/6. Now, you can add the numerators: 3/6 + 4/6 = 7/6. Since this is an improper fraction, you can convert it to the mixed number 1 1/6. On the other hand, say you're working on the problem 7/10 - 1/5. The common multiple in this case is 10, since 1/5 can be converted into a fraction with a denominator of 10 by multiplying it by 2: 1 x 2 = 2 and 5 x 2 = 10, so the new fraction is 2/10. You don't need to convert the other fraction at all. Just subtract 2 from 7, which is 5. The answer is 5/10, which can also be reduced to 1/2. Fortunately, multiplying fractions is pretty easy. If the fractions aren't already in the lowest terms, reduce them. Then, all you need to do is multiply the numerator by the numerator and the denominator by the denominator. For instance, to multiply 2/3 and 7/8, find the new numerator by multiplying 2 by 7, which is 14. Then, multiply 3 by 8, which is 24. Therefore, the answer is 14/24, which can be reduced to 7/12 by dividing both the numerator and denominator by 2. To divide fractions, start by making the fraction you want to divide by a reciprocal. Do this by turning it upside down so the numerator becomes the denominator and the denominator becomes the numerator. Then, multiply both numerators and both denominators together. For example, to solve 1/2 ÷ 1/6, flip 1/6 upside down so it becomes 6/1. Then just multiply 1 x 6 to find the numerator (which is 6) and 2 x 1 to find the denominator (which is 2). So, the answer is 6/2 which is equal to 3.
Question: What is a summary of what this article is about?
Add fractions with the same denominator by combining the numerators. Subtract fractions with the same denominator by subtracting the numerators. Find a common multiple Multiply fractions straight across. Divide fractions by flipping the second fraction upside down and multiplying straight across.

Fill up a small bowl with wet or dry dog food and place it outside near where the duck typically stays. You can use dry food, or you can wet it a bit with water.  If the duck is injured, it’s best to use wet dog food so the duck will get some water and avoid dehydration. You can also put out a bowl of water for an injured duck to get rehydrated. Find a place to hide where you can see the food bowl, but the duck will not be able to see you. Hide there with a net big enough to fit the duck.  A net with a handle will give you good leverage to be able to scoop up the duck without having to get too close. Get a net with an opening greater than 1 foot in diameter. A large fishing net is a good option. While the duck is eating the dog food, quietly sneak up behind it. Make your movements quick but quiet because you need to get up to the duck before it’s done eating, but you don’t want the duck to hear you coming. Keep the net hidden behind your back so the duck does not see it. When you get close enough to the duck for the net to reach,  swiftly bring the net down over the duck.  Grasp the duck by the neck while it is in the net to gently lift it off the ground. If the duck flies away before you can get the net out, try the method again the next day. Place the net on the ground and gently reach in to grasp the duck by the neck. Be careful not to pull the duck out with its wings tangled in the net. Gently work the net free from the duck's feet and wings to prevent injuring the duck. While holding the duck by the neck you can safely place it in a carrier for transport, or release it in a new location.
