Question

Ming drew the model below to represent the equation 24+12=_x(8+4) What is the missing value in Ming's equation?

Answer 1

Given:

The equation is:

`24+12=\_\_* (8+4)`

To find:

The missing value.

Solution:

We have,

`24+12=\_\_* (8+4)` ...(i)

Taking left hand side, we get

`24+12=3* 8+3* 4`

Taking 3 common, we get

`24+12=3* (8+4)` ...(ii)

On comparing (i) and (ii), we get

Missing value = 3

Therefore, the missing value in the given equation is 3.
