Divide number into the whole number part (32) and decimal number part (0.25). Divide the whole number part by 2 and note down the remainder in each step. Keep doing this until the result of the division is 1. 32/2 = 16, remainder 0 16/2 = 8, remainder 0 8/2 = 4, remainder 0 4/2 = 2, remainder 0 2/2 = 1, remainder 0 Now, write down the remainders in reverse order. Hence, binary of 32 is 100000. For the decimal part, keep on multiplying the decimal number by 2 and note down the digit before the decimal point in each step. Keep doing this until the result is a whole number. 0.25 × 2 = 0.5, digit before decimal is 0 0.5 × 2 = 1, digit before decimal is 1 Now, write down the digits. Hence, the binary of 0.25 is 0.01.Then, just join the whole number and the decimal part. Hence, binary of 32.25 = 100000.01
