  • Please solve: 1/2 + 3/4 |: 4/6. This is wrong. You cannot just sum the numerators when the denominators are different! Let us first find a common multiple of 2 and 4! Please enter a common multiple of 2 and 4: |: 2. This is wrong. 2 is no common multiple of 2 and 4, since 2 is not divisible by 4! So, let's try again! Please enter a common multiple of 2 and 4: |: 3. This is wrong. 3 is not a common multiple of 2 and 4, since 3 is not divisible by 2! So, let's try again! Please enter a common multiple of 2 and 4: |: 5. This is wrong. I see you are having a hard time with this. Hint: 2 * 4 = 8 is a possible solution. So, let's try again! Please enter a common multiple of 2 and 4: |: 8. Good, the solution is correct. There is also a smaller solution! Now apply this knowledge to the original task! Please solve: 1/2 + 3/4 |: 10/8. Good, the solution is correct, but not minimal. Please cancel common divisors in: 10/8 |: 1/4. This is wrong! Unfortunately, I cannot give any useful hints here. So, let's try again! Please cancel common divisors in: 10/8 |: 5/0. The denominator of a fraction cannot be 0. So, let's try again! Please cancel common divisors in: 10/8 |: 5/4. Good, the solution is correct and also minimal. Very nice! the interaction history: [solve(1/2+3/4),internal(1/2+3/4=4/6),solve(cm(2,4)),internal(cm(2,4)=2),solve(cm(2,4)),internal(cm(2,4)=3),solve(cm(2,4)),internal(cm(2,4)=5),solve(cm(2,4)),internal(cm(2,4)=8),solve(1/2+3/4),internal(1/2+3/4=10/8),solve(cancel(10/8)),internal(cancel(10/8)=1/4),solve(cancel(10/8)),internal(cancel(10/8)=5/0),solve(cancel(10/8)),internal(cancel(10/8)=5/4)] true.
