In a class of students, the ratio of boys to girls is 3:2. If the total number of students is 50, how many boys are there? (2023)

Step 1: Understand the ratio of boys to girls, which is 3:2.
Step 2: This means for every 3 boys, there are 2 girls.
Step 3: Let 'x' be a common multiplier. Then, the number of boys can be represented as 3x and the number of girls as 2x.
Step 4: Add the number of boys and girls together: 3x + 2x.
Step 5: This simplifies to 5x (since 3x + 2x = 5x).
Step 6: We know the total number of students is 50, so we set up the equation: 5x = 50.
Step 7: Solve for x by dividing both sides of the equation by 5: x = 50 / 5.
Step 8: Calculate x, which gives us x = 10.
Step 9: Now, find the number of boys by substituting x back into the equation for boys: 3x = 3 * 10.
Step 10: Calculate the number of boys, which is 30.
