<span>(5/8+19/36)-1/36
1) 5/8 = 45/72
2) 19/36 = 38/72
3) 45/72 + 38/72 = 83/72
4) 1/36 = 2/72
5) 83/72 - 2/72 = 81/72
6) 81/72 = 9/8 = одна целая 1/8</span>
1 928 - 630 : 126 * 156 = 1 148
1) 630 : 126 = 5
2) 5 * 156 = 780
3) 1 928 - 780 = 1 148
12 * 15 + 2 000 : 100 + 87 654 = 87 854
1) 12 * 15 = 180
2) 2 000 : 100 = 20
3) 180 + 20 = 200
4) 200 + 87 654 = 87 854
