What other times-tables can be constructed by splitting into equal groups and doubling? Give examples.

Correct Answer

Times-tables for even numbers can be constructed by doubling.

Examples: Times-18 table can be made by doubling times-9 (since $18 = 2 \times 9$ ). Times-16 table can be made by doubling times-8 (since $16 = 2 \times 8$ ). Times-12 table can be made by doubling times-6 (since $12 = 2 \times 6$ ). Times-20 table can be made by doubling times-10 (since $20 = 2 \times 10$ ).

For More Understanding

Explanation

Any even number can be split into two equal parts, making doubling a useful strategy. The chapter shows this helps students construct new times-tables from familiar ones.

Solution Steps

Times-tables for even numbers can be constructed by doubling.
Times-18 table can be made by doubling times-9 (since $18 = 2 \times 9$ ).
Times-16 table can be made by doubling times-8 (since $16 = 2 \times 8$ ).
Times-12 table can be made by doubling times-6 (since $12 = 2 \times 6$ ).
Times-20 table can be made by doubling times-10 (since $20 = 2 \times 10$ ).
