Worked Solution
Step 1: Write the value of each part:\n 5 tens = 5 × 10 = 50\n 6 ones = 6 × 1 = 6\n 7 tenths = 7 × 0.1 = 0.7\n 4 hundredths = 4 × 0.01 = 0.04\n
Step 2: Add them up using a place-value column:\n 50 + 6 = 56\n 0.7 + 0.04 = 0.74\n
Step 3: Combine: 56 + 0.74 = 56.74.\n
Step 4: Check by reading 56.74 back: tens digit 5 ✓, ones digit 6 ✓, tenths digit 7 ✓, hundredths digit 4 ✓.
Answer: 56.74
