Here are the solutions for Activity 3: Make equal. 1. Problem 1: 20 + 5 + _______ = 35 Step 1: Add the known numbers on the left side. 20 + 5 = 25 Step 2: Subtract this sum from the right side to find the missing number. 35 - 25 = 10 The missing number is 10 2. Problem 2: 15 + 15 + _______ = 45 Step 1: Add the known numbers on the left side. 15 + 15 = 30 Step 2: Subtract this sum from the right side to find the missing number. 45 - 30 = 15 The missing number is 15 3. Problem 3: 3 × 5 = 7 + _______ Step 1: Calculate the left side of the equation. 3 × 5 = 15 Step 2: Subtract 7 from 15 to find the missing number. 15 - 7 = 8 The missing number is 8 4. Problem 4: double 25 = 67 - _______ Step 1: Calculate "double 25". 2 × 25 = 50 Step 2: Subtract 50 from 67 to find the missing number. 67 - 50 = 17 The missing number is 17 5. Problem 5: 7 × 4 = 14 × _______ Step 1: Calculate the left side of the equation. 7 × 4 = 28 Step 2: Divide 28 by 14 to find the missing number. 28 ÷ 14 = 2 The missing number is 2 6. Problem 6: 6 × 3 = 85 - _______ Step 1: Calculate the left side of the equation. 6 × 3 = 18 Step 2: Subtract 18 from 85 to find the missing number. 85 - 18 = 67 The missing number is 67 7. Problem 7: 36 ÷ 3 = 20 - _______ Step 1: Calculate the left side of the equation. 36 ÷ 3 = 12 Step 2: Subtract 12 from 20 to find the missing number. 20 - 12 = 8 The missing number is 8 8. Problem 8: _______ + 75 = 125 - 25 Step 1: Calculate the right side of the equation. 125 - 25 = 100 Step 2: Subtract 75 from 100 to find the missing number. 100 - 75 = 25 The missing number is 25 Send me the next one 📸
