Compare the times-15 table with the times-5 table. What similarities and differences do you notice?

Correct Answer

Similarities: Both tables produce products ending in 5 or 0. All products are multiples of 5.

Differences: The times-15 products are 3 times larger than corresponding times-5 products. Example: 4×5=204 \times 5 = 20 while 4×15=604 \times 15 = 60. The difference between consecutive products is 5 in times-5 table but 15 in times-15 table.

For More Understanding

Explanation

The chapter shows that times-15 products are triple the times-5 products because 15=3×515 = 3 \times 5. For example, 4×15=60=3×(4×5)=3×204 \times 15 = 60 = 3 \times (4 \times 5) = 3 \times 20.

Solution Steps

  1. Compare the ending digits of products in both tables.

  2. Identify that all products are multiples of 5.

  3. Compare the magnitude of corresponding products in each table.

  4. Compare the difference between consecutive products in each table.
