Multiplying decimals You feed your dog 2.3 cups of food a day, and you need to bring enough food for a 4.5-day trip. Start by multiplying the digits, ignoring the decimal points, using the standard algorithm. 23 × 45 = 1,035. To decide where to put the decimal point, find the total number of decimal places in the original numbers: 2. The

We’ll learn how to add and subtract decimals using a standard algorithm. We will also learn how to multiply and divide decimals using a standard algorithm. And we’ll see that this knowledge can help us run a race, make soup, and even record a song!

Fluently add, subtract, multiply, and divide multi-digit decimals using the standard algorithm for each operation.

Learn how to multiply multi-digit decimals using the standard algorithm, and see examples that walk through sample problems step-by-step for you to improve your math knowledge and...

Learn how to use visual models, area models and the standard algorithm to teach students various strategies for multiplying decimals.

Mrs. Florczyk demonstrates how to multiply decimals using standard algorithm.

Jun 30, 2010 · Standard Multiplication Algorithm for Decimals. Why is 0.3 times 0.2 equal to 0.06, and not 0.6 like some may think? The rules for decimal multiplication and division follow directly from what we know about decimal place value and fraction arithmetic. Example: Multiple 0.3(0.2). Since and , multiplying 0.3(0.2) is the same as multiplying .

Apr 1, 2025 · Multiplying decimals. Multiplying decimals using the standard algorithm follows the same process as multi-digit multiplication with whole numbers. The only difference is the decimals points! Let’s look at the example 4.28 x 3.6.

In this engaging math lesson, students will learn how to multiply and divide decimals using the standard algorithm. They will practice multiplying two decimal numbers and dividing a decimal by another decimal. Students will also learn how to reason and estimate the product and quotient.

Review the standard algorithm for multiplication with two-digit whole numbers (i.e., 16 x 74). Tell students, "Today we are going to learn how to multiply decimals." Ask students to retell the steps needed to complete the standard algorithm with multi-digit multiplication.
