Ответ: Объяснение:
12,5₁₀ = 0*2⁰ + 0*2¹ + 1*2² + 1*2³ + 1/2¹ = 1100,1₂
12,5₁₀ = 4*8⁰ + 1*8¹ + 4/8¹ = 14,4₈
312,54₁₀ = 0*2⁰ + 0*2¹ + 0*2² + 1*2³ + 1*2⁴ + 1*2⁵ = 100111000,10001₂
312,54₁₀ = 0*8⁰ + 7*8¹ + 4*8² + 4/8¹ + 2/8² + 4/8³ + 3/8⁴ + 6/8⁵ = 470,42436₈
219,333₁₀ = 1*2⁰ + 1*2¹ + 0*2² + 1*2³ + 1*2⁴ + 0*2⁵ + 1*2⁶ + 1*2⁷ + 0/2¹ + 1/2² + 0/2³ + 1/2⁴ + 0/2⁵ = 11011011,01010₂
219,333₁₀ = 3*8⁰ + 3*8¹ + 3*8² + 2/8¹ + 5/8² + 2/8³ + 3/8⁴ + 7/8⁵ = 333,25237₈
