Question

approximate value of ( 1.9)(3.1) 2 is​

Answer 1

Answer:

12

Step-by-step explanation:

1.9×3.1×2= 11.78

the approximate value of 11.78 is 12 because rounding off of 11.78 nearest to 12

Answer 2

Given:

Some numbers for multiplication are given.

To Find:

Approximate value of ( 1.9)(3.1) 2

Step-by-step explanation:

• We know that when there is a bracket between the numbers that means we have to multiply the numbers.
• Now, In the given problem to find the approximate value first, we will change these numbers to round figures.
• We can change (1.9) to 2 and (3.1) to 3 as we will find approximate value only.
• So our new numbers are as follows.

        $(2)(3)2$

• We know that when there is a bracket between two numbers multiplication will take place.

        $2 \times 3\times 2=12$

So, the approximate value of ( 1.9)(3.1) 2 is 12.
