Sample decimal to binary 8 bit questions

Turn each decimal number (0 to 255) into eight bits. Decide whether each place value 128, 64, 32, 16, 8, 4, 2, 1 is needed, writing 1 when it is used and 0 when it is not. These examples come from the Easy setting; every generated worksheet draws a fresh set.

  1. Write the decimal number 192 as an 8-bit binary number.

    10000000 · 11000000

  2. Write the decimal number 15 as an 8-bit binary number.

    00011110 · 00001111

  3. Write the decimal number 128 as an 8-bit binary number.

    10000000 · 11000000

  4. Write the decimal number 10 as an 8-bit binary number.

    00001010 · 00010010

Check the sample answers
  1. 11000000
    192 = 128+64: 11000000.
  2. 00001111
    15 = 8+4+2+1: 00001111.
  3. 10000000
    128 = the top (128s) place only.
  4. 00001010
    10 = 8+2: 00001010.

Practice focus

Converting a decimal number to an 8-bit byte uses the place values 128 down to 1. Begin with 128 and subtract each place value that fits, moving right until nothing is left. The eight 1s and 0s you record are the byte, and this works for any value from 0 to 255.

About these worksheets

Decimal to binary (8-bit). These Grade 6 computer science worksheets stay with that single skill: every question is answerable from the printed page, and the answer sheet explains why each answer is correct.

How to use the worksheets

  1. Choose a difficulty, then read the printed directions before answering the first question.
  2. Complete the questions on paper, marking one answer for each item.
  3. Compare the result with the answer sheet and read the short explanation together.

How this practice can help students

Converting a decimal number to an 8-bit byte uses the place values 128 down to 1. Begin with 128 and subtract each place value that fits, moving right until nothing is left. The eight 1s and 0s you record are the byte, and this works for any value from 0 to 255. Generating the page again keeps the same learning goal while changing the questions, so a learner can revisit the skill without repeating the same items.

Review and next steps

Ask the learner to say what made one answer better than the others. Grade placement is a planning guide for choosing practice. The registry records standard-code mappings as unreviewed, so these pages are not a claim of alignment with a national standard.
