This reduces the D, to C, and lends 1, or 16 decimal to the first column. 16 decimal + 12 decimal - 15 decimal = 13 decimal, or D in the first column. The following columns require no borrowing, making the calculations simple. Since 1 was borrowed, C - A = 12 decimal - 10 decimal = 2, and 5 - 3 = 2 yielding the final result of 22D. In the case
When we need to round an answer to 2 decimal places, it means that we have to find the approximate value of a number up to the hundredths place, which is second to the right of the decimal point. For example, let us add 3.456 + 2.162 and round the answer to 2 decimal places. After adding the numbers, we get, 3.456 + 2.162 = 5.618.Then simply put the result to the right of a decimal expression of the number of hours to get the decimal time. Example 1: convert 5 hours and 45 minutes to decimal. Solution: divide 45 minutes by 60 to get .75 hours. Then simply put it after "5" to get the answer of 5.75. Example 2: a worker has logged 7 hours and 15 minutes.
1. Convert each digit to decimal, one by one. This results in the decimal values 0, 5, 13, and 12. 2. Convert each of these decimal numbers into 4 bits of binary. This gives us the binary values 0000, 0101, 1101, and 1100. 3. Put these binary values next to each other.
