Let’s solve each multiplication problem step by step. We’ll multiply the 4-digit number by the 2-digit number using the standard method — breaking it into two parts: first multiply by the ones digit, then by the tens digit (remembering to add a zero at the end), and finally add them together.

Problem 1: 1147 × 37
Step 1: Multiply 1147 by 7 (ones place)
1147 × 7 =
7×7=49 → write 9, carry 4
7×4=28 +4=32 → write 2, carry 3
7×1=7 +3=10 → write 0, carry 1
7×1=7 +1=8 → so we get
8029
Step 2: Multiply 1147 by 30 (tens place — so we’ll add a zero at the end)
1147 × 3 =
3×7=21 → write 1, carry 2
3×4=12 +2=14 → write 4, carry 1
3×1=3 +1=4
3×1=3 → so 3441, then add a zero →
34410
Step 3: Add the two results
8029
+34410
=
42439
✔ Check: 1147 × 37 = 42439

Problem 2: 3220 × 35
Step 1: Multiply 3220 by 5
3220 × 5 =
5×0=0
5×2=10 → write 0, carry 1
5×2=10 +1=11 → write 1, carry 1
5×3=15 +1=16 → so
16100
Step 2: Multiply 3220 by 30 → add a zero at the end
3220 × 3 =
3×0=0
3×2=6
3×2=6
3×3=9 → so 9660, then add zero →
96600
Step 3: Add
16100
+96600
=
112700
✔ Check: 3220 × 35 = 112700

Problem 3: 6201 × 89
Step 1: Multiply 6201 by 9
9×1=9
9×0=0
9×2=18 → write 8, carry 1
9×6=54 +1=55 → so
55809
Step 2: Multiply 6201 by 80 → add a zero
6201 × 8 =
8×1=8
8×0=0
8×2=16 → write 6, carry 1
8×6=48 +1=49 → so 49608, then add zero →
496080
Step 3: Add
55809
+496080
=
551889
✔ Check: 6201 × 89 = 551889

Problem 4: 1913 × 54
Step 1: Multiply 1913 by 4
4×3=12 → write 2, carry 1
4×1=4 +1=5
4×9=36 → write 6, carry 3
4×1=4 +3=7 → so
7652
Step 2: Multiply 1913 by 50 → add a zero
1913 × 5 =
5×3=15 → write 5, carry 1
5×1=5 +1=6
5×9=45 → write 5, carry 4
5×1=5 +4=9 → so 9565, then add zero →
95650
Step 3: Add
7652
+95650
=
103302
✔ Check: 1913 × 54 = 103302

Problem 5: 6938 × 67
Step 1: Multiply 6938 by 7
7×8=56 → write 6, carry 5
7×3=21 +5=26 → write 6, carry 2
7×9=63 +2=65 → write 5, carry 6
7×6=42 +6=48 → so
48566
Step 2: Multiply 6938 by 60 → add a zero
6938 × 6 =
6×8=48 → write 8, carry 4
6×3=18 +4=22 → write 2, carry 2
6×9=54 +2=56 → write 6, carry 5
6×6=36 +5=41 → so 41628, then add zero →
416280
Step 3: Add
48566
+416280
=
464846
✔ Check: 6938 × 67 = 464846

Problem 6: 3111 × 27
Step 1: Multiply 3111 by 7
7×1=7
7×1=7
7×1=7
7×3=21 → so
21777
Step 2: Multiply 3111 by 20 → add a zero
3111 × 2 = 6222 → add zero →
62220
Step 3: Add
21777
+62220
=
83997
✔ Check: 3111 × 27 = 83997
