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* (9+11.3)` and the value of this expression is 162.4.

Step-by-step 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* (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* (9+11.3)=8* (20.3)\\8* (9+11.3)=162.4`

Therefore, the numerical expression is
`8* (9+11.3)` and the value of this expression is 162.4.

Answer 2

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 * 20.3=162.4`
