Question

lets play \whats missing?\ work to find the missing amount in each equation.
equation 2: 0.85 + ? = 1.00
make an expression that shows one way to make 1.00 starting at 0.85.
0.85
0.85
0.05 0.10 +
0.15 0.20

Explanation:

Step1: Identify the missing value

We need to find the number that when added to 0.85 gives 1.00. Let the missing number be \( x \). So the equation is \( 0.85 + x = 1.00 \). To find \( x \), we use the subtraction property of equality: \( x = 1.00 - 0.85 \).

Step2: Calculate the difference

Calculate \( 1.00 - 0.85 \). \( 1.00 - 0.85 = 0.15 \). So the missing number is 0.15. The expression is \( 0.85 + 0.15 = 1.00 \).

Answer:

The missing amount is 0.15, and the expression is \( 0.85 + 0.15 = 1.00 \)
