While students are only expected to memorize multiplication tables up to 20, learning the Table of 75 is an excellent math trick. Because 75 is exactly three-quarters of 100 (3/4), knowing its multiples helps tremendously with calculating percentages, money, and time.
Notice the pattern in the last two digits of the Table of 75: They always repeat the sequence 75, 50, 25, 00 continuously!
| Multiplication | Result |
|---|---|
| 75 × 1 | 75 |
| 75 × 2 | 150 |
| 75 × 3 | 225 |
| 75 × 4 | 300 |
| 75 × 5 | 375 |
| 75 × 6 | 450 |
| 75 × 7 | 525 |
| 75 × 8 | 600 |
| 75 × 9 | 675 |
| 75 × 10 | 750 |
| Multiplication | Result |
|---|---|
| 75 × 11 | 825 |
| 75 × 12 | 900 |
| 75 × 13 | 975 |
| 75 × 14 | 1050 |
| 75 × 15 | 1125 |
| 75 × 16 | 1200 |
| 75 × 17 | 1275 |
| 75 × 18 | 1350 |
| 75 × 19 | 1425 |
| 75 × 20 | 1500 |
To multiply any number by 75 mentally, use the 'Three-Quarters' trick. Since 75 is (3/4) of 100:
Example: 75 × 16
75% is mathematically represented as **3/4**. (75/100 simplified by dividing both by 25).
