Mrs. Fowler has 28 students in her class, and 16 of them are boys.
Elan Coil [88]
We subtract 28 - 16 and get the number of girls 
so lets do that 
28 - 16 = 12 
now we know the unsimplified ratio os 12 to 16 
simplifed girls 12 ÷ 4 = 3 
simplified boys 16 ÷ 4 = 4 
since it says (girls to boys) we put girls first then boys
so it would become 3 : 4 
Or the answer is B.) 3 : 4

siniylev [52]

Answer:

6.

Step-by-step explanation:

This is [p(2+h))  - p(2) ] /  ((2 + h - 2)

= [ 6(2) + h) + 7 - (6(2) + 7)] / h

=  (  12 + 6h + 7 - 12 - 7) / h

=  6h / h

= 6.
