1. **State the problem:** Simplify the expression $(1,4:5+19:20)*2-1,5$. 2. **Clarify notation:** The commas likely represent decimal points, so rewrite as $(1.4 \div 5 + 19 \div 20) \times 2 - 1.5$. 3. **Apply division:** Calculate each division: $$1.4 \div 5 = 0.28$$ $$19 \div 20 = 0.95$$ 4. **Add the results:** $$0.28 + 0.95 = 1.23$$ 5. **Multiply by 2:** $$1.23 \times 2 = 2.46$$ 6. **Subtract 1.5:** $$2.46 - 1.5 = 0.96$$ 7. **Final answer:** $$\boxed{0.96}$$
