1. The problem is to convert the number 148 into Roman numerals. 2. Roman numerals are formed by combining letters that represent values: I=1, V=5, X=10, L=50, C=100, D=500, M=1000. 3. Break down 148 into parts: 100 + 40 + 8. 4. 100 is represented by C. 5. 40 is represented by XL (50 - 10). 6. 8 is represented by VIII (5 + 3). 7. Combine these parts: C + XL + VIII = CXLVIII. 8. Therefore, 148 in Roman numerals is CXLVIII.
