Question

Write the numerical expression for the product of 8 and the sum of 9 and 11.3. Then evaluate it.

Answer 1

Solution: The numerical expression is $8\times (9+11.3)$ and the value of this expression is 162.4.

Explanation:

The sum of 9 and 11.3 is written as $(9+11.3)$.

The product of 8 means the expression should multiply by 8.

According to the given information the the product of 8 and the sum of 9 and 11.3 is written as $8\times (9+11.3)$.

To evaluate the value of the expression first we have to add 9 and 11.3 after that multiply the result by 8.

$8\times (9+11.3)=8\times (20.3)\\8\times (9+11.3)=162.4$

Therefore, the numerical expression is $8\times (9+11.3)$ and the value of this expression is 162.4.

Answer 2

Answer:

162.4

Step-by-step explanation:

To write the numerical expression for the product of 8 and the sum of 9 and 11.3 we need to follow these steps:

Sum of 9 and 11.3 is given as follows:

$(9+11.3)$

Now the product of 8 and the sum of 9 and 11.3 is:

$8(9+11.3)$

So the required expression is:

$8(9+11.3)$

Solving the above expression we get:

$8(9+11.3)=8(20.3)=8 \times 20.3=162.4$
