Исходное выражение: 1 + 1/2 ÷ k = 4 + 3/4 ÷ 2 + 3/8
Решение:1 + 1/2 ÷ k = 4 + 3/4 ÷ 2 + 3/81 + 1/2 ÷ k = 4 + 3/8 + 3/81 + 1/2 ÷ k = 4 + 6/81 + 1/2 ÷ k = 4 + 3/41 + 1/2 ÷ k = 16/4 + 3/41 + 1/2 ÷ k = 19/4Multiplying through by 4k to eliminate the fraction:4k + 2 = 19kSubtracting 4k from both sides:2 = 15kk = 2/15
Ответ: k = 2/15
Исходное выражение: 1 + 1/2 ÷ k = 4 + 3/4 ÷ 2 + 3/8
Решение:
1 + 1/2 ÷ k = 4 + 3/4 ÷ 2 + 3/8
1 + 1/2 ÷ k = 4 + 3/8 + 3/8
1 + 1/2 ÷ k = 4 + 6/8
1 + 1/2 ÷ k = 4 + 3/4
1 + 1/2 ÷ k = 16/4 + 3/4
1 + 1/2 ÷ k = 19/4
Multiplying through by 4k to eliminate the fraction:
4k + 2 = 19k
Subtracting 4k from both sides:
2 = 15k
k = 2/15
Ответ: k = 2/15
