How to Find the Missing Addend in Decimal Addition Problems
FAQs on Adding Decimals with Missing Addends: Class 5 Maths Worksheet
1. How do you find a missing addend in decimals?
To find a missing addend in a decimal addition problem, you simply subtract the given addend from the total sum. This inverse operation reveals the unknown value.
- Step 1: Identify the total sum (the number after the '=' sign).
- Step 2: Identify the known addend (the number being added).
- Step 3: Subtract the known addend from the total sum.
- Example: In the equation 0.62 + ___ = 1.40, you would calculate 1.40 - 0.62. The result, 0.78, is the missing addend.
2. What are decimals with 2 digits?
Decimals with 2 digits, also known as two-digit decimals or hundredths, are numbers that have exactly two digits appearing after the decimal point. These are a key part of the Class 5 Maths syllabus.
- The first digit after the decimal point represents the tenths place.
- The second digit represents the hundredths place.
- For example, in the number 0.94, '9' is in the tenths place and '4' is in the hundredths place.

- Algebraic Thinking: It introduces the fundamental concept of solving for unknowns in an equation.
- Number Sense: It strengthens the understanding of place value, especially tenths and hundredths.
- Attention to Detail: It reinforces the critical rule of aligning decimal points in all calculations.
8. What is the easiest way to solve 2-digit decimal addition with a missing number?
The easiest and most reliable method is to convert the addition problem into a subtraction problem. This is a core strategy taught in Class 5 maths for finding a missing number.
- Equation: Given Addend + Missing Addend = Sum
- Solution Method: Sum - Given Addend = Missing Addend
- This approach avoids guessing and provides a clear, step-by-step process to find the correct answer every time.
