🔍 Key Concepts

• Number bases: how Base 10 (decimal) compares to Base 2 (binary) • Place values in binary (1, 2, 4, 8, 16, …) and how they add up • How to convert a small decimal number to binary by summing powers of 2

💭 Think About

• List the powers of 2 (1, 2, 4, 8, …) and find which combination adds up to 7 • Look at each option and convert it back from binary to decimal to see which equals 7 • Check how many binary digits (bits) you actually need to represent the value 7

✅ Before You Answer

• Remember that binary digits from right to left have values 1, 2, 4, 8, 16, … • For each choice, multiply each binary digit (0 or 1) by its place value and add them up • Verify that the correct binary representation for 7 uses only the powers of 2 that sum exactly to 7 with no extra or missing value
