5250:25 = 210 (тг) - на 6 дней одному ребёнку.
210:6 = 35 (тг) - на 1 день одному ребёнку.
35*30 = 1050 (тг) - на 1 день тридцати детям.
1050*14 = 14700 (тг) - на две недели на 30 человек.

5250/25=210 тенге на одного ребенка за 6 дней
210/6=35 тенге в день на ребенка
35*30=1050 на 30 человек в день
1050*14 (это две недели)=14700 тенге
в последнем действии надо уточнить, сколько две недели-12 или 14 дней,на эту цифру и умножить

Надинэ: т.е. если школьная неделя, то 1050*12=12600
Надинэ: а если пятидневка, то 1050*10=10500 тенге
Надинэ: удачи
