Question

Write two multiplication equations in which both factors are odd numbers. Write a comparison statement for each equation. (*Hint* we use these to compare <, >, =) Do the work on a separate piece of paper. Then use words and numbers for reasoning.

a. (3 × 5 = 15), (2 × 7 = 14); 15 > 14
b. (1 × 9 = 9), (5 × 3 = 15); 9 < 15
c. (7 × 7 = 49), (3 × 11 = 33); 49 > 33
d. (9 × 3 = 27), (5 × 5 = 25); 27 > 25

Answer 1

Multiplication equations involving odd numbers yield positive products that can be compared using comparison statements. For example, (7 × 3 = 21) and (5 × 5 = 25) lead to the comparison of 21 < 25.

Step-by-step explanation:

When creating multiplication equations where both factors are odd numbers, we obtain products that can be compared using comparison statements (<, >, =). Here are two examples of such equations:

1. (7 × 3 = 21)
2. (5 × 5 = 25)

The comparison statement for these products is 21 < 25, meaning that the product of 7 and 3 is less than the product of 5 and 5.

Using the multiplication rules, when two positive numbers are multiplied, such as in these equations, the result is always a positive number. These guidelines are foundational and help ensure accurate arithmetic in mathematics.
