If there are 12 boys in the class and 14 girls, what is the ratio of boys to all the students in the class?

Any is very appreciated! (picture is provided below)not sure how to do this at all won't lie

Merrida uses a pattern in the multiplication table below to find ratios that are equivalent to 7: 9. if merrida multiplies the first term, 7, by a factor of 6, what should she do to find the other term for the equivalent ratio? multiply 9 by 1. multiply 9 by 6. multiply 9 by 7. multiply 9 by 9.

What would the rule be for the reflection of y=-3
