Кислотные оксиды - ангидриды кислот. То есть от каждой кислоты надо "отнять" воду. Пишем гипотетические реакции разложения, чтобы справа образовывалась вода:
1) HNO2 = ... + H2O
2HNO2 = N2O3 + H2O
2) H2MnO4 = ... + H2O
H2MnO4 = MnO3 + H2O
3) H3PO4 = ... + H2O
2H3PO4 = P2O5 + 3H2O
4) H4Sb2O7 = ... + H2O
H4Sb2O7 = Sb2O5 + 2H2O
5) HNO3 = ... + H2O
2HNO3 = N2O5 + H2O
6) H3BO3 = ... + H2O
2H3BO3 = B2O3 + 3H2O

Как видите, при отщеплении воды из соединения должен уйти весь водород (ну и часть кислорода). Значит, именно под водород мы и подстраиваемся. Если водорода четное количество, то молекул воды будет в два раза меньше (не забудьте вычесть из соединения необходимый для образований этих молекул кислород). Если же нечетное количество, просто берем две молекулы кислоты. Главное не забывать, что есть многоосновные кислоты).
