1. Выполните умножение: 1) 6.8*3.2: 2) 8,6*9,36; 3)0,49*2,8; 4) 38,55*0,8; 5) 67.25*4; 6) 0,085*0,48; 7) 6,89*0,1; 8) 6,89*0,01.

Решение:

1. \( 6.8 \times 3.2 = 21.76 \)
2. \( 8.6 \times 9.36 = 80.496 \)
3. \( 0.49 \times 2.8 = 1.372 \)
4. \( 38.55 \times 0.8 = 30.84 \)
5. \( 67.25 \times 4 = 269 \)
6. \( 0.085 \times 0.48 = 0.0408 \)
7. \( 6.89 \times 0.1 = 0.689 \)
8. \( 6.89 \times 0.01 = 0.0689 \)

Ответ: 21.76; 80.496; 1.372; 30.84; 269; 0.0408; 0.689; 0.0689.
