How to Solve Decimal Multiplication Equations with a Missing Number?
FAQs on Multiplying Decimals by 1-Digit Numbers: Find the Missing Factor
1. How do you find the missing factor in decimal multiplication?
To find the missing factor in a decimal multiplication equation, you simply divide the product by the known factor. This process uses the inverse operation of multiplication. For example, in the equation 0.6 × ___ = 2.4, you would solve it by dividing 2.4 by 0.6, which gives you the missing factor, 4. This method is essential for solving missing number multiplication problems with decimals.
2. What is the trick for multiplying decimals by 1-digit numbers?
The easiest trick is to first ignore the decimal point and multiply the numbers as if they were whole numbers, then place the decimal point in the answer. After multiplying, count the total number of decimal places in the original decimal factor and ensure the product has the same number of decimal places. For example, to multiply 1.2 × 3:
- First, multiply 12 × 3 = 36.
- Since 1.2 has one decimal place, the product must also have one.
- So, the final answer is 3.6.

This activity builds crucial numerical reasoning and problem-solving skills related to operations with decimals. Students who use this worksheet develop a deeper understanding of equation balancing, reinforce their multiplication facts, and improve their accuracy with decimal place value, which are fundamental for more advanced maths.
8. What is the first step to solve a problem like 0.7 × ___ = 3.5?
The first step is to identify that you need to find a missing number, which requires using the inverse operation of multiplication: division. To solve for the blank, you must set up a division problem where you divide the product (3.5) by the known factor (0.7). The calculation 3.5 ÷ 0.7 will give you the missing factor, which is 5.
9. What topic does this 'Multiplying Decimals - Missing Factor' worksheet cover for Class 5?
This worksheet specifically covers the Class 5 Maths topic of decimal multiplication where one of the factors is a missing single-digit whole number. It is designed for Grade 5 students to practice and reinforce their understanding of the relationship between multiplication and division with decimals, requiring them to find the unknown value in an equation.
10. Are there visual models to understand decimal multiplication?
Yes, visual models like area grids or number lines are excellent tools for understanding how decimal multiplication works. While this specific worksheet focuses on numerical practice, these models are often used in classrooms to introduce the concept. For example:
- An area model (grid) can visually represent 0.4 × 3 as 3 groups of 4 tenths.
- A number line can show repeated jumps of a decimal length to find the total product.
These aids help build a strong conceptual foundation for multiplying decimals.
