Hello there!
For this you simply need to give both fractions a common denominator!
The easiest way to do this specific problem would be to make the denominator 12. Why 12? Because 4 x 3 = 12.
So:
1/4 --> ?/12 --> 1 (3) / 12 --> 3/12
2/3 --> ?/12 --> 2 (4) / 12 --> 8/12
Total amount of time means the sum (adding them together).
When adding fractions, you MUST have a common denominator! (Which is what we just did).
So 3/12 + 8/12 = (8+3) / 12 = 11/12 hours
Notice how the denominator stayed the same? When adding/subtracting fractions, the denominator stays the same! :)
Hope this helped!

Answer:
No solution
Step-by-step explanation:
5(x + 4) – x = 4(x + 5) – 1
x = ?
Solution:
5(x+4)−x=4(x+5)−1
Apply Distributive property:
- (5)(x)+(5)(4)−x=(4)(x)+(4)(5)−1
- 5x+20−x=4x+20−1
Combine Like Terms:
- (5x−x)+(20)=(4x)+(20−1)
- 4x+20=4x+19
- 4x+20=4x+19
Subtract 4x from both sides:
Subtract 20 from both sides:
There isn't any solutions.
