Question

Wo decimal numbers, each with one decimal place, are multiplied. Use the products 3.5 × 8.5, 6.4 × 7.5, and 8.4 × 5.5 to help you decide which of the following statements are true. Choose all that apply.

a. The product of 3.5 × 8.5 is greater than 30.
b. The product of 6.4 × 7.5 is less than 50.
c. The product of 8.4 × 5.5 is equal to 45.
d. The product of 3.5 × 8.5 is equal to 29.75.

Answer 1

To determine which statements are true, calculate the products of the given decimal numbers and compare them to the statements.

Step-by-step explanation:

To determine which statements are true, we can calculate the products of the given decimal numbers.

a. The product of 3.5 × 8.5 is 29.75, which is less than 30, so statement a is false.

b. The product of 6.4 × 7.5 is 48, which is less than 50, so statement b is true.

c. The product of 8.4 × 5.5 is 46.2, which is not equal to 45, so statement c is false.

d. The product of 3.5 × 8.5 is 29.75, which is not equal to 29.75, so statement d is false.

Therefore, the correct statements are b. The product of 6.4 × 7.5 is less than 50.
