564+884
125-1000

Answer 1

Пошаговое объяснение:

127 * 4 = 508

508 : 127 = 4

508 : 4 = 127

645 : 9 = 645/9 = 71 6/9 = 71 2/3

71 2/3 * 9 = 215/3 * 9 = 215/1 * 3 = 645/1 = 645

564 + 884 = 1448

1448 - 564 = 884

1448 - 884 = 564

125 - 1000 = -875

-875 + 1000 = 125

125 - (-875) = 125 + 875 = 1000

Answer 2

1)127 * 4 = 508
2)508: 127 = 4
1)6459645/9 = 71 6/9 = 71 2/3
2)71 2/3 9215/3* 9 = 215/1 * 3 = 645/1 * = 645
1)564 +884 = 1448
2)1448-564 = 884
1)1251000=-875
2)-875+ 1000 = 125
