To find out how many boys and girls there are in the fifth grade at Franklin School, you need to use the information that there are 3 boys for every 4 girls. Here's how you can solve it step by step:
Step 1: Determine the number of equal groups. In this case, there are two groups: boys and girls.
Step 2: Add the numbers in the ratio. In this case, 3 + 4 = 7. This means that for every 7 students, 3 are boys and 4 are girls.
Step 3: Determine the value of each group. Divide the total number of students in the grade (140) by the sum of the ratio parts (7). 140 ÷ 7 = 20. This shows that each group represents 20 students.
Step 4: Multiply the value of each group by the corresponding ratio part to find the number of students in each group. The 3:4 ratio indicates that there are 3 parts for boys and 4 parts for girls.
- Boys: 3 parts × 20 = 60 boys
- Girls: 4 parts × 20 = 80 girls
Therefore, there are 60 boys and 80 girls in the fifth grade at Franklin School.
