Number of boys enrolled is 105
<em><u>Solution:</u></em>
Given that, At a local preschool there is s as ratio of 3 boys to every 4 girls
There are 245 total preschoolers
Ratio of boys and girls = 3 : 4
Number of boys : number of girls = 3 : 4
Let the number of boys be 3x
Let the number of girls be 4x
Total number of preschoolers = 245
Therefore,
number of boys + number of girls = 245
3x + 4x = 245
7x = 245
x = 35
Number of boys = 3x = 3(35) = 105
Thus number of boys is 105

There are 5 little lines between 0 and -1, so each line represents 1/5.
B is located 3 lines to the left of -1, so it would be located at - 1 3/5.
Am absolute value is a positive number so - 1 3/5 would become 1 3/5.
The answer would be A. 1 3/5
