Well you have

$\frac{2}{3}A=\frac{4}{5}B\Rightarrow B=\frac{5}{6}A$

so

$A+B=\frac{11}{6}A$

Since A+B is an integer and is between 20 and 24, we must have that

$A+B=\frac{11}{6}\left(12\right)=22$

so

Since A+B is an integer and is between 20 and 24, we must have that

For both fractions I made their denominator equal, so:

$\frac{2}{3}=\frac{10}{15}\text{}\text{and}\text{}\frac{4}{5}=\frac{12}{15}.$

The smallest multiple they have on common is 60, so to get equality this means we need 6 times$\frac{2}{3}$ and 5 times $\frac{4}{5}$ . Hence the answer must be a multiple of 11, so the answer is 22.

The smallest multiple they have on common is 60, so to get equality this means we need 6 times
