What is the answer to this question?

Answer 1

A

Explanation:

Proportions can be any number so other statements can't be always true

Answer 2

A. Class X has a greater proportion of boys than Class Y

Explanation:

- Before choosing any objective, first relate the two proportions.

Multiply class Y by 2:

`{ \rm{y = 2(4 : 5)}} \\ { \rm{y= 8:10}}`

- So it can be related with class X as the ratios have a common proportion of girls; 10

`{ \rm{x= 9:{ \green{10}}}} \\ { \rm{y = 8:{ \green{10}}}}`

- By observation, we see that class X has a greater number of boys than in class Y
