Answer:
A. 2:1
B. 1:2
Step-by-step explanation:
Since girls are 2/3 of class, the remaining 1/3 are boys. So,
[tex] \frac{1}{3} (boys) \: and \: \frac{2}{3} (girls) \\ \frac{1}{3} \infty \frac{2}{3} \\ \frac{1 \infty 2}{3} \\ that \: is \: 1 \infty 2 \: for \: boys \: to \: girls \: ratio[/tex]
NB: I used the infinity sign for rationality sign, because I couldn't get the sign here
