Пошаговое объяснение:
1) 21 / 15 * 100 = 7 / 5 * 100 = 140
2) 45 * 4 = 180
3) 2 *5 = 10
4) 7 * 20 = 140
5) 6 * 100 = 600
6) 48 / 8 * 100 = 600
7) 35 / 7.7 * 100 = 3500 / 7.7 = 35000 / 77 = 454 42/77
1) 15% = 21
1% = 21/15
1% = 1,4
100% = 1% * 100
100% (или A) = 1,4 * 100 = 140
2) С остальными аналогично
25% = 45
1% = 1,8
100% = 180
3) 20% = 2
1% = 0,1
100% = 10
