Question

Реши уравнения.

х ⋅ 150 = 600 000 : 2000

1000 : х = 1500 : 300

65 872 + х = 100 ⋅ 10 000

278 367 – х = 1 000 000 : 1000

Answer 1

Х · 150 = 600000 : 2000
х · 150 = 300
х = 300 : 150
х = 2
2 · 150 = 600000 : 2000
300 = 300

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

65872 + х = 100 × 10000
65872 + х = 1000000
х = 1000000 - 65872
х = 934128
65872 + 934128 = 100 × 10000
1000000 = 1000000

278367 - х = 1000000 : 1000
278367 - х = 1000
х = 278367 - 1000
х = 277367
278367 - 277367 = 1000000 : 1000
1000 = 1000
