Calculate 3/7 of 56: Finding Girls in a First Grade Class

There are 56 students in a 1st grade school class.

$\frac{3}{7}$ of them are girls.

How many girls are there in the class?

To solve this problem, we'll follow these steps:

• Step 1: Identify the total number of students - 56 students.
• Step 2: Recognize that the fraction of students who are girls is $\frac{3}{7}$.
• Step 3: Multiply the total number of students by the fraction to find the number of girls.

Now, let's work through each step:
Step 1: We are given that there are 56 students in total.
Step 2: The fraction of the students who are girls is $\frac{3}{7}$.
Step 3: To find the number of girls, compute:

$\text{Number of girls} = 56 \times \frac{3}{7}$

Perform the calculation:

$56 \times \frac{3}{7} = \frac{56 \times 3}{7}$

Simplify by canceling the common factor between 56 and 7:

$= \frac{168}{7} = 24$

Therefore, the solution to the problem is 24.
