๐9 ร 5 combination
Since 45 = 9 ร 5, the 45 times table can also be reached by multiplying the 9 times table by 5, or the 5 times table by 9.

How to Practice the 45 Times Table
Learning times tables requires consistent practice with the right strategies. Here are proven methods to master specifically the 45 times table:
Use 45รn = 50รn โ 5รn: multiply by 50, then subtract five times the original number. 45ร6 = 300 โ 30 = 270.
Or multiply the 9 times fact by 5: 45รn = 5ร(9รn).
Connect it to vinyl records: singles traditionally spin at 45 RPM, a useful everyday anchor.
Skip count by 45s out loud: 45, 90, 135, 180, 225, 270, 315, 360, 405, 450.
Common Mistakes When Learning the 45 Times Table
Many students make similar mistakes when learning this times table. Being aware of these common errors helps you avoid them and learn more effectively.
Subtracting the wrong amount in the 50โ5 trick
Solution: 45รn = 50รn โ 5รn, not 50รn โ 5. Make sure to subtract five times the original number. 45ร6 = 300 โ 30 = 270.
Losing track of odd vs. even multipliers
Solution: Since 45 is a multiple of 5, results still end in 0 or 5 depending on whether the multiplier is even or odd โ the same rule as the 5 times table applies.
