Question

let’s play “what’s 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 + 0.15
now, complete the equation.
0.85 + ? = 1.00

Explanation:

Step1: Identify the operation

To find the missing number in the equation \( 0.85 + ? = 1.00 \), we use the inverse operation of addition, which is subtraction. The formula to find the missing addend is \( ? = 1.00 - 0.85 \).

Step2: Perform the subtraction

Calculate \( 1.00 - 0.85 \). Subtracting the two decimals, we get \( 1.00 - 0.85 = 0.15 \).

Answer:

\( 0.15 \)
