Answer:

The correct option A.

Step-by-step explanation:

Total numbers of students = 24.

Number of boys = 10

Number of girls = 24 - 10 = 14

Jeff claims that the ratio of boys to girls in this class must be 5:12.

The ratio of the number of boys to the total number of students is

\frac{boys}{students}=\frac{10}{24}=\frac{5}{12}=5:12

Therefore Jeff found the ratio of the number of boys to the total number of students.

The ratio of boys to girls in this class is

\frac{boys}{girls}=\frac{10}{14}=\frac{5}{7}=5:7

Therefore the ratio of boys to girls in this class is 5:7.

Option A is correct.

katovenus [111]
Well think about it this way -9 times what equals 252 you already know x is going to be a negative number because the outcome is positive so try doing the problem backwards 252/-9=-28 so x=-28
