Activity 1: Fill in the missing number *a) Step 1: Identify the operation. The equation is 30.5 + missing number = 30.9. Step 2: Isolate the missing number by subtracting 30.5 from 30.9. Missing number = 30.9 - 30.5 Step 3: Perform the subtraction. 30.9 - 30.5 = 0.4 The missing number is 0.4. *b) Step 1: Identify the operation. The equation is 725.13 + missing number = 725.45. Step 2: Isolate the missing number by subtracting 725.13 from 725.45. Missing number = 725.45 - 725.13 Step 3: Perform the subtraction. 725.45 - 725.13 = 0.32 The missing number is 0.32. *c) Step 1: Identify the operation. The equation is 5.203 - missing number = 3.15. Step 2: Isolate the missing number by subtracting 3.15 from 5.203. Missing number = 5.203 - 3.15 Step 3: Perform the subtraction. 5.203 - 3.15 = 2.053 The missing number is 2.053. Activity 2: Calculate the following by using any method *a) Step 1: Set up the addition problem, aligning the decimal points. 324.12 + 10.63 Step 2: Add the numbers column by column, starting from the rightmost digit. r 324.12 \\ + 10.63 \\ 334.75 The sum is 334.75.
