Final answer:
Two numbers that multiply together to equal 1.6 can include 1.6 and 1, or other factor pairs like 1.6 and 1, or numbers in scientific notation that, when calculated, result in the product of 1.6.
Step-by-step explanation:
To find two numbers that multiplied together equal 1.6, we could choose a variety of pairs, but one straightforward pair is 1.6 and 1. In this case, 1.6 × 1 equals 1.6. Additionally, we could use scientific notation and also manipulate the power of ten. For instance, 1.6 × 10¹, which is the same as 1.6, can be multiplied by 10⁻⁹ (or 1/10), resulting in 1.6 still.
Numerous other combinations are possible if we consider fractions or decimal numbers that multiply to give 1.6. The process of determining such numbers involves finding a factor pair that results in the desired product, similar to the examples provided in the instructional material.
Further exploration of the concept of factor pairs and significant figures in calculations can deepen understanding of number operations and scientific notation in mathematics.
