1. CONVERTION OF DECIMAL TO OCTAL TLE 7 ICT

2. By the end of the lesson: Identify steps in conversion of Decimal to Octal 2. Convert Decimal to Octal

3. GUIDE QUESTIONS: How do we convert Decimal to Octal?

4. The decimal number 185 is equivalent to ___ in Octal. DIVISION QUOTIENT REMAINDER 185/8 23 1 23/8 2 7 2/8 2 8 10

5. 1. Divide the number by 8 ( 8 is the base of the octal so divisor here). 185/8 23/8 2/8

6. 2. Store the remainder in an array ( it will be: 0,1,2,3,4,5,6,7 because of divisor 8). REMAINDER 1 7 2

7. 3. Repeat the above two steps until the quotient is zero. QUOTIENT 23 2

8. 4. Copy the remainder from bottom to top. REMAINDER 1 7 2

9. REVIEW What are the steps in converting Decimal number to Octal? Divide the decimal number in 8. Write down the Quotient and Remainder in the column. Repeat steps 1 and 2, until the quotient is zero. Take the remainder from bottom to top.
