1. The problem is to perform multiple operations without converting numbers into fractions or other forms. 2. When multiplying numbers, multiply the numerators together and the denominators together if fractions are involved. 3. Since the user requested no conversion into fractions, we will multiply whole numbers or decimals directly. 4. For example, multiplying 3 and 4 gives $3 \times 4 = 12$. 5. If decimals are involved, multiply as usual: $1.5 \times 2 = 3$. 6. Always keep the numbers in their original form and multiply directly without converting to fractions or other forms. 7. This approach simplifies multiplication and avoids unnecessary conversions.
