Multiplication Word Problems

18 × 30 = (10 + 8) × 30 = 300 + 240 = 540. Or directly: 18 × 3 = 54, then add a zero: 540. This is basic multiplication using the distributive property or standard algorithm.

40 × 85 = 40 × (80 + 5) = 3200 + 200 = 3400. Alternatively: 85 × 4 = 340, then add a zero: 3400. This tests ability to multiply with multiples of 10 and apply the distributive property.

4000 × 41 = 4000 × (40 + 1) = 160,000 + 4,000 = 164,000. Or: 4 × 41 = 164, then add three zeros: 164,000. This tests multiplication with large numbers and place value understanding.

17 × 34 = 17 × (30 + 4) = 510 + 68 = 578. Alternatively: 17 × 2 = 34, then 34 × 17 = 578. This tests two-digit multiplication skills using the distributive property or standard algorithm.

Distance = Speed × Time = 30 km/h × 15 h = 450 km. This is a straightforward application of the distance formula. At 30 km per hour for 15 hours, multiply 30 by 15 to get the total distance traveled.

Total marbles = marbles per box × number of boxes = 42 × 16 = 672. Using the distributive property: 42 × 16 = 42 × (10 + 6) = 420 + 252 = 672. This tests multiplication in a word problem context.

Multiply 42 by 31 using the distributive property: 42 × 31 = 42 × 30 + 42 × 1 = 1260 + 42 = 1302. You can also do 40 × 31 = 1240, then add 2 × 31 = 62.

Multiply 85 by 12: 85 × 12 = 85 × 10 + 85 × 2 = 850 + 170 = 1020. The answer B (1255) is close but incorrect.

Total teeth = number of adults × teeth per adult = 83 × 32. Using partial products: 83 × 30 = 2490, plus 83 × 2 = 166, gives 2656.

Multiply 56 by 32: 56 × 32 = 56 × 30 + 56 × 2 = 1680 + 112 = 1792. Answer D is correct.

Minutes in 24 hours = 24 × 60 = 1440. This is a standard time conversion - one hour has 60 minutes, so a full day (24 hours) has 24 times that amount.

Each family member has 2 towels (small + bath). With 5 members: 5 × 2 = 10 towels total. Don't be distracted by the specific towel types - the problem only asks for the total count.

Monday, Tuesday, Friday: 3 meals each = 3 × 3 = 9 meals. Remaining 4 days (Wed, Thu, Sat, Sun): 4 meals each = 4 × 4 = 16 meals. Total: 9 + 16 = 25 meals.

Total eggs = 4 cartons × 6 eggs = 24 eggs. Good eggs = total - bad = 24 - 2 = 22. The subtraction step is crucial - don't stop at 24.

Three friends with 5 cars each: 3 × 5 = 15 cars. Two friends with 2 cars each: 2 × 2 = 4 cars. Total: 15 + 4 = 19 cars.

Each child brought 6 balls. With 4 children: 4 × 6 = 24 balls total. Don't overcomplicate - the problem states they brought balls, not that they're sharing.

Total balloons = 16 packets × 85 balloons = 1360. Use distributive property: 16 × 85 = 16 × 80 + 16 × 5 = 1280 + 80 = 1360.

Total earnings = 36 books × £27 per book = £972. Using partial products: 36 × 27 = 36 × 20 + 36 × 7 = 720 + 252 = £972.

First multiply: 95 × 5 = 475 and 80 × 10 = 800. Then add: 475 + 800 = 1275. The order of operations (multiplication before addition) is key here.

24 squared (24 × 24) equals 576. You can calculate this as 24 × 20 + 24 × 4 = 480 + 96 = 576, or memorize common square numbers.

Each toy car has 5 rows of 5 seats, so 5 × 5 = 25 seats per car. With 5 cars: 5 × 25 = 125 seats total. This is a two-step multiplication problem.

Four pizzas sliced into four parts each means: 4 × 4 = 16 slices total. This is a simple multiplication problem.

Three post offices with five workers each: 3 × 5 = 15 workers total. This is a straightforward multiplication problem.

Three meals per day for seven days (a normal week): 3 × 7 = 21 meals. This combines multiplication with time calculation.

Fourteen puzzles with 270 pieces each: 14 × 270 = 3780 pieces. You can calculate this as (10 × 270) + (4 × 270) = 2700 + 1080 = 3780.
