If you need to find x% of y, just flip it to y% of x and the answer will be the same but easier to find.

​

For Example: 4% of 75 = 75% of 4 which is 3

                                           16% of 25 = 25% of 16 which is 4

If you multiply a single digit by 9, the sum of the digits in the answer will be 9 as well.

​

For Example: 9 x 3 = 27 (2+7=9)

                            9 x 6 = 54 (5+4=9)

If you multiply a single digit even number by 6, the answer will end with the same digit you are multiplying by. The number in the ten's place of the answer will be half of the number in the one's place.

​

For Example: 6 x 2 = 12 (1 is half of 2)

                            6 x 8 = 48 (4 is half of 8)
