Answer: 105
Step-by-step explanation:
Given : At a local preschool there is a ratio of 3 boys to every 4 girls.
Also, there are 245 Total preschoolers enrolled.
Let the number of boys be 3x and the number of girls be 4x.
Then According to the question, we have
[tex]3x+4x=245\\\\\Rightarrow\ 7x=245\\\\\Rightarrow\ x=\dfrac{245}{7}=35[/tex]
Now, the number of boys enrolled = 3(35)=105
Hence, there are 105 boys.
If there are 245 total preschoolers, there will be 105 boys.
Fraction of boys = 3/7
Fraction of girls = 4/7
Total number of students = 245
The number of boys will be:
= 3/7 × 245.
= 105 boys
Therefore, there are 105 boys in the school.
