Multiples of 5
5 times even number
Rule:
a. Write half of the even multiplier down and put 0 at the end.
Examples:
5 x 2; Half of 2 is 1. Put 0 behind the 1 to form your answer.
Hence 5 x 2 = 10.
5 x 12; Half of 12 is 6. Put 0 behind the 6 to form your answer.
Hence 5 x 12 = 60.
5 times odd number
Rule:
a. Write half of the odd multiplier down and ignore the decimal
point. The number you see is your product.
Examples:
5 x 1; Half of 1 is 0.5. Ignore the decimal point. Hence 5 x 1 = 5.
5 x 19; Half of 19 is 9.5. Ignore the decimal point. Hence 5 x 19 = 95.
