Solution for Exercise 1 on Pages 58, 59 Math 5 Textbook: Multiplying Decimals with Decimals, Set up and Solve:

Guidance for Exercise 1 on Pages 58, 59 Math 5 Textbook

Exercise:
Set up and solve:
a) 25.8 x 1.5 ; b) 16.25 x 6.7;
c) 0.24 x 4.7; d) 7.826 x 4.5;

Solution Method:
Students should master the rule of multiplying decimals:
- Set up the calculation as usual: Place the first factor on the top row; place the second factor below the first one, aligning digits in columns; the decimal points of the two factors do not necessarily need to align; place the multiplication sign in between the two factors on the left side of the calculation
- Perform multiplication as with natural numbers
- Use the decimal point to separate digits in the product corresponding to the decimal places of the two known factors, starting from the right.

Frequently Asked Questions

What are the steps to set up multiplication for decimals in Exercise 1?

To set up the multiplication of decimals, place the first factor on the top row and the second factor below it. Align the digits in columns, but the decimal points do not need to align, as the multiplication sign is placed on the left.

How should students perform multiplication when working with decimal numbers?

Students should perform multiplication as they would with whole numbers, multiplying each digit individually and carrying over if necessary. After completing the multiplication, adjust the decimal point in the product based on the total number of decimal places in the factors.

What is the correct method for finding the decimal point in the product?

To find the decimal point in the product, count the total number of decimal places in both factors. Start from the right of the product and move left by that total number of places to correctly place the decimal point.

Can you provide examples of decimal multiplication problems from Exercise 1?

Examples from Exercise 1 include problems such as 25.8 x 1.5, 16.25 x 6.7, 0.24 x 4.7, and 7.826 x 4.5. Each problem follows the method of setting up the calculation and adjusting the decimal point in the final product.
