Question

# Each row in the classroom has 11 girls and 12 boys. There are 9 rows in that class. Write a numerical expression to show the number of students in that class.

## 11(9 + 12)    11(9 × 12)    9(11 × 12)    9(11 + 12) Hint:

## The correct answer is: 9(11 + 12)

### In the question it is given that,Number of girls = 11Number of boys = 12Total number of rows= 9We have to find the numerical expression to show the number of students in that class.Total number of boys and girls = 11+12So, the numerical expression to show the number of students in that class is 9(11 + 12).Therefore, the correct option is d, i.e., 9(11 + 12).

In distributive property, when a factor is to be multiplied with the sum of two numbers, we do not directly add the two numbers and then multiply the sum with the factor. Rather, we multiply both the numbers with the factor differently and then add the multiplication value.
