Change the problem to make it easier to multiply. For example, you can multiply one number by two if you multiply the other by 1/2. Try making your own and solving it in the top row. =**__x 5__**= ||= =**28**= =**__x 5__**= ||= =**24**= =**__x 5__**= ||=  ||= =**148**= =**__x 5__**= ||=  ||= =**248**= =**__x 50__**= || =**128**= =**__x 50__**= || =**468**= =**__x 500__**= ||  ||   ||   ||   ||   ||   ||   ||   ||   ||   ||   ||   ||   ||   ||   ||   ||   ||   ||   ||   ||   ||   ||   ||   ||   ||   ||   ||   ||   ||   ||   ||   ||   ||   ||   ||   ||

Multiply by Splitting
When one number of a multiplication pair has two digits, try splitting that number into two parts by dividing it by 2. Example: 9 x 12 Split 12 into two parts: 12=6x2 Instead of 9x12 (9x6x2) think 9 x 6 and then double it. 9x6=54 Double 54 and you get 108.

1. 8 x 16

2. 5 x 22

3. 6 x 18

4. 7 x 14

5. 9 x 16

6. 12 x 24
