Identifying the Missing Amount
Determining missing amounts in numerical equations involves finding the unknown value that completes the equation. Understanding place value and number relationships is crucial for accurate results.
Examples of Simple Equations with Missing Amounts
- 5 + ? = 10
- ? – 3 = 7
- 12 ÷ 4 = ?
Methods for Solving Missing Amounts: Determine The Missing Amount For Each Of The Following
Inverse Operations
Invert the operation on the other side of the equation to isolate the missing amount.
Example:5 + ? = 10 – Subtract 5 from both sides: 5 + ? – 5 = 10 – 5 – ? = 5
Estimation
Estimate the missing amount by rounding numbers and using mental math.
Example:27 + ? ≈ 50 – Round 27 to 30 and 50 to 40 – 30 + ? ≈ 40 – ? ≈ 10
Trial and Error
Guess the missing amount and check if it satisfies the equation.
Example:? – 6 = 12 – Guess ? = 15 – 15 – 6 = 12 (benar) – ? = 15
