The 15 times table
Fifteen minutes is a quarter of an hour — and the 15s are just the 10s and 5s added together.
- 15×1=15
- 15×2=30
- 15×3=45
- 15×4=60
- 15×5=75
- 15×6=90
- 15×7=105
- 15×8=120
- 15×9=135
- 15×10=150
- 15×11=165
- 15×12=180
How to learn the 15s
Each line means “15 groups of”. So 15 × 4 = 60 means four groups of 15 make 60. Every answer is just 15 more than the one before: 15, 30, 45, 60, 75…
The highlighted facts, 15 × 7 = 105, 15 × 9 = 135 and 15 × 11 = 165, are the ones learners usually find hardest. The tips below give you a way into each one.
Self-test: press “Hide answers”, say each answer out loud, then tap a fact to check it.
In real life
Three quarter-hours are 15 × 3 = 45 minutes, the length of many school lessons.
Three ways to make the 15s easy
Ten, plus half of it
Find 10 × the number, then add half of that.
15 × 6 = 60 + 30 = 90Quarter hours
15 × 4 = 60 minutes, one hour. 15 × 2 = 30, half past.
15 × 4 = 60Half of the 30s
Multiply by 30 (3s with a zero), then halve.
15 × 8 = 240 ÷ 2 = 120Spot the pattern
Last digits of 15 × 1 to 15 × 10:
5, 0, 5, 0. Odd steps end in 5 and even steps end in 0: 15, 30, 45, 60, 75, 90…
An hour every 4 steps. 15 × 4 = 60, 15 × 8 = 120, 15 × 12 = 180 — every 4 steps adds another 60.
Both 3s and 5s. Every 15s answer is in the 3s table and the 5s table.
The matching division facts
Every multiplication fact gives you a division fact for free. If 15 × 7 = 105, then 105 ÷ 15 = 7.
- 15 ÷ 15 = 1
- 30 ÷ 15 = 2
- 45 ÷ 15 = 3
- 60 ÷ 15 = 4
- 75 ÷ 15 = 5
- 90 ÷ 15 = 6
- 105 ÷ 15 = 7
- 120 ÷ 15 = 8
- 135 ÷ 15 = 9
- 150 ÷ 15 = 10
- 165 ÷ 15 = 11
- 180 ÷ 15 = 12
