What factor is paired with 6 to give 54

The answer is 9.

How I remember the 9 times tables is this.

1*9=9

2*9=18 (18, think 1+8=9)

3*9=27 (27, think 2+7=9)

4*9=36 (36, think 3+6=9)

5*9=45 (45, think 4+5=9)

and so on

So for 6*9, subtract 1 from 6, which gives you the first digit 5.

Then, think 5 + what gives me 9?

5+4, right?

So your answer is 54.
