Ming drew the model below to represent the equation 24 + 12 = blank x (8 + 4). A model with 3 rows of 8 and 3 rows of 4. What is the missing value in Ming's equation?

Given:

The equation is:

A model with 3 rows of 8 and 3 rows of 4.

To find:

The missing value in Ming's equation.

Solution:

We have,

          ...(i)

A model with 3 rows of 8 and 3 rows of 4. Using this information, we get

Taking out the common factor 3, we get

              ...(ii)

On comparing (i) and (ii), we get the missing value is 3.

Therefore, the missing value in Ming's equation is 3.
