At a local preschool there is a ratio of 3 boys to every 4 girls if there are 245 total preschoolers enrolled how many boys

The total number of boys = 105

Step-by-step explanation:

The ratio of boys to girls = 3: 4

⇒ For every 3 boys, there are 4 girls.

Now, total number of students = 245

Let the common ratio of boys to girls is k.

So, 3k + 4k = 245

or, 7k = 245

⇒ k = 245/7 = 35

⇒ k = 35

Hence, the number of boys = 3k = 3 x 35 = 105

and number of girls = 4k = 4 x 35 = 140
