FAQs on Advanced Multiplying Decimals in Columns – Class 5 Maths Practice
1. How do you multiply decimals in columns in Grade 5?
To multiply decimals in columns for Grade 5, you first multiply the numbers as if they were whole numbers and then place the decimal point correctly in the product. The process involves a few simple steps:
- Align the numbers on the right side, ignoring the decimal points for now.
- Multiply the numbers exactly as you would with whole numbers using the column method.
- Count the total number of decimal places in both of the original numbers (the factors).
- Place the decimal point in your answer (the product) so it has the same number of decimal places you just counted.

6. What is the rule for placing the decimal point in the product?
The rule for placing the decimal point in the final answer (the product) is straightforward and based on counting. After you multiply the numbers, you must:
- Count the total number of digits after the decimal point in the first number.
- Count the total number of digits after the decimal point in the second number.
- Add these two counts together.
- Place the decimal point in your answer so that it has this total number of digits after it. For example, if 1.25 (2 decimal places) is multiplied by 0.5 (1 decimal place), the answer will have 2 + 1 = 3 decimal places.
