Question

А ÷одну целую семь петидесятых = пять педисят седьмых ÷ одну вторую

Answer 1

А ÷одну целую семь петидесятых = пять педисят седьмых ÷ одну вторую

А: 1 7/50= 5/57: 1/2
А= 5/57: 1/2• 1 7/50
А= 5/57• 2/1• (50•1+7)/50
А= 10/57• 57/50
Сокращаем 57 и 57 на 57; 10 и 50 на 10
А= 1/1• 1/5
А=1/5

Проверка
1/5: 1 7/50= 5/57: 1/2
1/5: (1•50+7)/50= 5/57• 2/1
1/5: 57/50= 10/57
1/5• 50/57= 10/57
1/1• 10/57= 10/57
10/57=10/57
