Answer:
C
Step-by-step explanation:
y / 4 = 39 / 30
y / 4 = 1.3
y / 4 * 4 = 1.3 * 4 (What you do to on side you also do to the other)
y = 5.2
So, your answer should be C, 5.2
I think that number one is C. I'll try and solve the second one as well.
Ok, so at first this question seems tricky, since 5 does not go into 25. However, you can't have a percentage of 1 person. Since 5 goes into 25 5 times, then we will go with that. So multiply 3 x 5 to get 15 girls. Because you can't have a fraction of a single person.
