    Answer:

    11

    Step-by-step explanation:

    first you sum the ratios

    1+2=3

     \frac{2}{3}  \times x = 22 \\ 2x = 66 \\ x = 33 \\ this \: mean \: that \: we \: have \: 33 \:  \\ students

    since boys are 22 , all we have to do is to subtract 22 from 33 the answer would be 11

    therefore we have 11 girls.
