8.
2x = 124
x = 124 : 2
x = 62

96 : x = 16
x = 96 : 16
x = 6

x : 3 = 0,7
x = 0,7 * 3
x = 2,1

3x : 4 = 3 : 5

3x = 3*4 : 5
3x = 12 : 5
x = 12 : 15
x = 4 : 5 = 0,8

9.
S = 6a²

1) 6*4² см² = 96 см²

2) 50 мм = 5 см
6*5² см² = 150 см²

3) 4/5 м = 8 дм
6*8² дм² = 384 дм²

4) 2 1/2 дм = 25 см
6*25² см²= 3750 см²
