Question

Which expression has a product of 3.249?

a) 0.15 * 0.72
b) 1.5 * 0.72
c) 1.5 * 0.72
d) 1.5 * 0.72

Answer 1

None of the provided expressions result in the product of 3.249. There may be a mistake or a typo in the choices given by the student. The last expression shows a product close to 3.249 but seems to include incorrect numbers.

Step-by-step explanation:

To determine which expression has a product of 3.249, we need to multiply the numbers within each expression given:

1. 0.15 × 0.72 = 0.108
2. 1.5 × 0.72 = 1.08
3. 1.5 × 2.16 = 3.24 (Notice that this option is not represented accurately in the student's question and may be a typo since the other options are repeated, if it were actually 1.5 × 2.16, then the product would be closer to the desired result)

It appears that there might be a mistake in the options provided by the student, as none of these products equal 3.249, and the option that would give a product close to 3.249 seems to include a typo or incorrect numbers. Make sure to check the original problem for any errors and confirm the correct numbers to use for the multiplication.
