What two decimals give you a product close to 5.5?

Answer 1

Product of 4.21 and 1.31 gives 5.5

Product of 3.21 and 1.72 gives 5.5

Solution:

Given that,

We have to find two decimals that gives a product close to 5.5

So, when the two decimals are added, the product must be close to 5.5

Let us consider the following two decimals

4.21 and 1.31

Let us multiply 4.21 and 1.31 and check if their product is close to 5.5

`4.21 * 1.31 = 5.5151 \approx 5.5`

Thus, product of 4.21 and 1.31 gives a product close to 5.5

Similarly, consider two decimals 3.21 and 1.72

Let us multiply 3.21 and 1.72 and check if their product is close to 5.5

`3.21 * 1.72 = 5.5212 \approx 5.5`

Thus product of 3.21 and 1.72 gives 5.5
