All you do is add them all together...
20 + 11.4 + 11.4 + 4.5 + 4.5 + 0.45 + 0.45 + 0.45 + 0.45 = 53.6Kg
(note that 0.45 is 450g in Kg, When adding things such as weight or length you want to make sure that they are all in the same unit)
If you use the common denominator of .5 for both sides of the ratio, you will arrive at 3:5 as a simplified form.

Answer:
t = 41.6 (the 6 is repeating)
Step-by-step explanation:
2.5t + 350 = 3t + 225
Subtract 2.5t from both sides to get:
350 = 3t + 225
Now subtract 225 from both sides to get:
125 = 3t
Divide both sides by three.
t = 41.6 (the 6 is repeating)
The correct answer is A, it has -1. While B's got 1.
