How to Solve Multiplication Equations with a Missing Integer Factor
FAQs on Multiplication of Integers: Find the Missing Factor (Class 6 Worksheet)
1. How to find a missing factor in multiplication involving integers?
To find the missing factor in a multiplication equation with integers, you use the inverse operation, which is division. Simply divide the product by the known factor, making sure to follow the rules for integer division.
- The Formula: Missing Factor = Product ÷ Known Factor.
- Example: In the equation -3 × ___ = 21, you calculate 21 ÷ (-3).
- Solution: The missing factor is -7 because a negative number multiplied by a negative number gives a positive product.
2. What is the formula for the missing factor?
The formula to find a missing factor is based on division: Missing Factor = Product ÷ Known Factor. This rule is fundamental for solving multiplication equations where one number is unknown and is a key step towards understanding basic algebra.
3. How to multiply integers in Grade 6?
To multiply integers in Grade 6, first multiply the numbers ignoring their signs, then determine the sign of the answer using these rules:
- Positive × Positive = Positive (e.g., 4 × 5 = 20)
- Negative × Negative = Positive (e.g., -4 × -5 = 20)
- Positive × Negative = Negative (e.g., 4 × -5 = -20)
- Negative × Positive = Negative (e.g., -4 × 5 = -20)
4. How do you solve multiplication with missing digits when integers are involved?
Solving multiplication with a missing factor or digit requires two main steps when integers are involved. First, find the numerical value using division, and second, determine the correct sign.
- Step 1: Divide the numbers. For 7 × ___ = -49, calculate 49 ÷ 7 = 7.
- Step 2: Determine the sign. Since the product (-49) is negative and the known factor (7) is positive, the missing factor must be negative.
- Final Answer: The missing factor is -7.
