Answer:
Step-by-step explanation to find the fraction and number of boys and girls in the school, we can follow these steps:
Calculate the number of girls.
Calculate the number of boys.
Find the fraction of girls.
Find the fraction of boys.
Let's go through these steps:
Number of girls: Total number of students×7/12=540
Total number of girls;12/7=540× 12/7=315
The number of boys: Total number of students−Number of girls=540−315=225
Fraction of girls: Number of girls/Total number of students=315/540=7/12
Fraction of boys: Number of boys/Total number of students=225/540=5/12
So, the fraction of girls is 7/12 and the fraction of boys is 5/12
The number of girls is 315, and the number of boys is 225.
.
Answer:
Number of girls in the school = 315
Number of boys in the school = 225
Fraction of boys in the school = [tex]\frac{5}{12}[/tex]
Step-by-step explanation:
There are 540 students in the school.
No. of girls in the school = [tex]540 \times \frac{7}{12} = 45 \times 7 = 315[/tex]
No. of boys in the school = Total number of students - No. of girls
= 540 - 315
= 225
Now, fraction left of boys = Total fraction of students - Fraction of girls
= [tex]1-\frac{7}{12}[/tex]
= [tex]\frac{12-7}{12}[/tex]
= [tex]\frac{5}{12}[/tex]
