To convert a binary number to decimal, multiply each digit by the corresponding power of 2 and sum the results. Step 1: Identify the binary number and assign powers of 2 to each digit, starting from the rightmost digit with 2^0. The binary number is 1111_2. 1 · 2^3 + 1 · 2^2 + 1 · 2^1 + 1 · 2^0 Step 2: Calculate the value of each power of 2. 2^3 = 8 2^2 = 4 2^1 = 2 2^0 = 1 Step 3: Substitute the power values and perform the multiplications. 1 · 8 + 1 · 4 + 1 · 2 + 1 · 1 8 + 4 + 2 + 1 Step 4: Sum the results to get the decimal equivalent. 8 + 4 + 2 + 1 = 15 The decimal equivalent of binary 1111 is 15. The correct option is 15. Send me the next one 📸
