Question

Помогите!!!!!!!!!!!!!!!!!Найди неизвестное число.

Answer 1

1) (340 754 - k) : 6 = 23 800
340 754 - k = 23 800 × 6
340 754 - k = 142 800
k = 340 754 - 142 800
k = 197 954

2) m × 80 - 32 965 = 31 835
m × 80= 31 835 + 32 965
m × 80= 64 800
m = 64 800 : 80
m = 810

3) 70 × (n:200) = 16 450
n : 200 = 16 450 : 70
n : 200 = 235
n = 235 × 200
n = 47 000
