Enter the number that is missing from the equation represented by the models: 2.44 ÷ _____ = 1.22.
Understand the Problem
The question is asking to determine the missing number in the division equation represented by the given models. Based on the models shown, we need to find the number that, when divided into 2.44, equals 1.22.
Answer
The missing number is $2$.
Answer for screen readers
The missing number is ( 2 ).
Steps to Solve
-
Understanding the Division Equation
The equation we are working with is ( 2.44 \div x = 1.22 ). Our goal is to find the value of ( x ). -
Rearranging the Equation
To solve for ( x ), we can rearrange the division equation into multiplication. This gives us: $$ x = \frac{2.44}{1.22} $$ -
Performing the Division
Now, we calculate ( x ) by dividing ( 2.44 ) by ( 1.22 ): $$ x = 2.44 \div 1.22 $$
When we calculate this, we find that: $$ x = 2 $$
The missing number is ( 2 ).
More Information
When you divide ( 2.44 ) by ( 1.22 ), you are essentially determining how many times ( 1.22 ) fits into ( 2.44 ). Since ( 1.22 ) fits exactly twice into ( 2.44 ), we conclude that the missing number is ( 2 ).
Tips
- Dividing incorrectly by not keeping track of decimal places. Always align decimal points during division.
- Forgetting to switch from division to multiplication properly when rearranging the equation.
