Here are the solutions for the addition problems: a) 65 + 52 Step 1: Separate into tens and ones. 65 = 6 tens and 5 ones. 52 = 5 tens and 2 ones. Step 2: Add the ones and tens separately. Total ones: 5 + 2 = 7 ones. Total tens: 6 + 5 = 11 tens. Step 3: Regroup the tens. Since there are 11 tens, we can regroup 10 tens into 1 hundred. 11 tens = 1 hundred and 1 ten. Step 4: Combine the regrouped values. We have 1 hundred, 1 ten, and 7 ones. 100 + 10 + 7 = 117 The sum is 117. b) 76 + 63 Step 1: Separate into tens and ones. 76 = 7 tens and 6 ones. 63 = 6 tens and 3 ones. Step 2: Add the ones and tens separately. Total ones: 6 + 3 = 9 ones. Total tens: 7 + 6 = 13 tens. Step 3: Regroup the tens. Since there are 13 tens, we can regroup 10 tens into 1 hundred. 13 tens = 1 hundred and 3 tens. Step 4: Combine the regrouped values. We have 1 hundred, 3 tens, and 9 ones. 100 + 30 + 9 = 139 The sum is 139. c) 86 + 65 Step 1: Separate into tens and ones. 86 = 8 tens and 6 ones. 65 = 6 tens and 5 ones. Step 2: Add the ones and tens separately. Total ones: 6 + 5 = 11 ones. Total tens: 8 + 6 = 14 tens. Step 3: Regroup the ones. Since there are 11 ones, we can regroup 10 ones into 1 ten. 11 ones = 1 ten and 1 one. Step 4: Regroup the tens. We started with 14 tens and added 1 ten from the regrouped ones, making a total of 14 + 1 = 15 tens. Since there are 15 tens, we can regroup 10 tens into 1 hundred. 15 tens = 1 hundred and 5 tens. Step 5: Combine the regrouped values. We have 1 hundred, 5 tens, and 1 one. 100 + 50 + 1 = 151 The sum is 151. Send me the next one 📸
