Year Five Mathematics Worksheets
Math is an important subject that kids need to learn as they grow up. One of the important concepts they will come across is multiplying and dividing numbers by powers of 10. In this article, we will be discussing what multiplying and dividing numbers by powers of 10 means and how it can be used in real-life examples.
A power of 10 is a number that is multiplied by 10 multiple times. For example, 10 to the power of 2 is 10 x 10 = 100, and 10 to the power of 3 is 10 x 10 x 10 = 1000. When we multiply a number by a power of 10, we add as many zeros to the end of the number as the power of 10. For example, if we multiply 50 by 10 to the power of 2, we get 50 x 100 = 5000.
When we divide a number by a power of 10, we remove as many zeros from the end of the number as the power of 10. For example, if we divide 5000 by 10 to the power of 2, we get 5000 ÷ 100 = 50.
Now that we know what multiplying and dividing numbers by powers of 10 means, let’s see how it can be used in real-life examples. Imagine you want to find the weight of an object in grams. If the weight is given in kilograms, you can multiply the weight by 1000 to convert it to grams. For example, if the weight of an object is 2 kilograms, you can multiply it by 1000 to get 2 x 1000 = 2000 grams. Similarly, if the weight of an object is given in grams and you want to convert it to kilograms, you can divide the weight by 1000. For example, if the weight of an object is 2000 grams, you can divide it by 1000 to get 2000 ÷ 1000 = 2 kilograms.
In conclusion, multiplying and dividing numbers by powers of 10 is an important concept in math that kids need to understand. It helps to convert between different units of measurement and makes it easier to work with larger and smaller numbers. By understanding this concept, kids will be well-equipped to handle more complex mathematical problems in the future.
