Ask a class which tables feel scary, and the bigger ones usually top the list. The table of 15 deserves a better reputation. It turns up in quarter-hours on a clock, in packs of items at the shop, and in scores in a tennis game. It also leads straight into the tables of 30 and 45. In this guide you’ll find the full table, a chart, seven memory tricks, solved examples and a worksheet with answers, so you can learn it in a way that actually sticks.
What Is the Table of 15?
The table of 15 is simply what you get when you multiply 15 by 1, 2, 3 and onwards. Each answer is 15 more than the last one: 15, then 30, then 45, and so on. If you ever forget a result, you can add 15 to the line above and get back on track.
Most students are surprised by how quickly it clicks once they notice the patterns hiding inside it. We’ll get to those shortly.

Multiplication Chart for 15
Here is the whole table on one page. Read each column as “15 times the number on top equals the number below”.
× | 1 | 2 | 3 | 4 | 5 | 6 | 7 | 8 | 9 | 10 |
15 | 15 | 30 | 45 | 60 | 75 | 90 | 105 | 120 | 135 | 150 |

A small tip: copy this chart by hand and stick it above your study desk. Writing it out yourself helps more than you’d think, and seeing it every day does the rest.
List the Multiples of 15
Multiples of 15 are the numbers you land on when you count in jumps of 15. The first twenty are:
15, 30, 45, 60, 75, 90, 105, 120, 135, 150, 165, 180, 195, 210, 225, 240, 255, 270, 285, 300
Look closely and you’ll spot a few handy things:
- Every one of them divides evenly by both 3 and 5.
- The last digit is always 5 or 0, switching back and forth.
- They alternate between odd and even.
- Add up the digits and you always get a multiple of 3. Take 135: 1 + 3 + 5 = 9.
15 Times Table: Easy Tricks to Memorise
You don’t have to cram this one. Try these tricks and pick the ones that suit you.
Trick 1: Split 15 into 10 and 5
Since 15 = 10 + 5, you can break any problem into two easy ones.
15 × 8 = (10 × 8) + (5 × 8) = 80 + 40 = 120
15 × 13 = 130 + 65 = 195
Trick 2: Multiply by 10, then add half
Take the number times 10, then add half of that. It’s the same idea as Trick 1, just quicker once you’re used to it.
15 × 6 → 60, half of 60 is 30, so 60 + 30 = 90
Trick 3: Watch the last digit
Odd multipliers end in 5 and even multipliers end in 0. If you work out 15 × 7 and your answer ends in 0, you know straight away that something slipped.
Trick 4: Halve it, then use 30
With an even number, halve it and multiply by 30.
15 × 16 = 8 × 30 = 240
15 × 14 = 7 × 30 = 210
Trick 5: Count in jumps of 30
Every two steps in the table adds 30. The odd ones go 15, 45, 75, 105, 135. The even ones go 30, 60, 90, 120, 150.
Trick 6: Picture a clock
A quarter of an hour is 15 minutes. So four quarters make 60 (one hour), eight make 120 (two hours), and twelve make 180 (three hours). When a number has a picture attached, it’s much harder to forget.
Trick 7: Say it out loud, then write it from memory
Chant the table in a steady rhythm, then try writing it without peeking. Do this for a few minutes a day for a week. Little and often beats one long session.
Solved Examples Using the Table of 15
Example 1: A packet has 15 biscuits. How many biscuits are there in 9 packets?
15 × 9 = 135 biscuits
Example 2: Riya reads 15 pages a day. How many pages will she read in 12 days?
15 × 12 = 180 pages
Example 3: A small bus carries 15 passengers per trip. How many can it carry in 7 trips?
15 × 7 = 105 passengers
Example 4: 225 chairs are set out in rows of 15. How many rows are there?
225 ÷ 15 = 15 rows
Example 5: How many minutes are there in 6 quarter-hours?
15 × 6 = 90 minutes
Where Do We Use the Table of 15 in Real Life?
- Time: Quarter-hours, class periods and meeting slots often come in blocks of 15 minutes.
- Money and shopping: Packs of 15, bulk prices and splitting bills.
- Sports: In tennis, the first points in a game are counted as 15, 30 and 40.
- Later maths: Factors, multiples, LCM, HCF, fractions and finding 15% of a number all lean on this table.

Common Mistakes to Avoid
- Mixing up the endings. An odd multiplier should never give an answer ending in 0.
- Adding 10 instead of 15. It happens more often than you’d expect when students are rushing. Add 15 each time, or use the 10 + 5 split.
- Slipping on the carry. For bigger problems like 15 × 17, split it as 170 + 85 = 255 and you’ll avoid most errors.
- Learning it by rote only. If you only memorise, one forgotten line can throw you off. Use the tricks to double-check yourself.

Tips for Parents and Teachers
- Keep practice short and playful. A two-minute “quick fire” round at breakfast works well.
- Bring in real objects: coins, counters or a clock face make 15 × 4 = 60 easy to see.
- Ask children to explain how they got an answer. Explaining is the best test of understanding.
- When a child gets one wrong, stay calm. It usually points to one small gap, not a lack of ability.
Conclusion
The table of 15 feels hard only until you notice its patterns: the 5-and-0 endings, the jump of 30 every two steps, and the easy 10 + 5 split. Keep the chart handy, try a few tricks, and work through the worksheet a couple of times. Before long, you’ll be answering without a second thought.
