Реши уравнения. х ⋅ 150 = 600 000 : 2000 1000 : х = 1500 : 300 65 872 + х = 100 ⋅ 10 000 278 367 – х = 1 000 000 : 1000

Х ⋅ 150 = 600 000 : 2000
x+150=600000:2000
x+150=300
x=300-150
x=150

150×150 = 600 000 : 2000

1000 : х = 1500 : 300
1000:x=5
x=1000:5
x=200

1000:200=1500:300

65 872 + х = 100 ⋅ 10 000
65872+x=1000000
x=1000000-65872
x=934128

65872+934128=100×10000

278 367 – х = 1 000 000 : 1000
278367-x=1000
x=278367-1000
x=277367

278367-277367=1000000:1000
Вот и все!
