Answer 1

6,4 pounds

Explanation:

First, let's the given numbers into improper fractions:

`1 (2)/(3) = (1 * 3 + 2)/(3) = (5)/(3)`

`2 (2)/(5) = (2 * 5 + 2)/(5) = (12)/(5)`

Now, we can find how much does the 2nd bar weigh by multiplying the 1st bar's weight by 5/3 times:

`(5)/(3) * (12)/(5) = (60)/(15) = 4`

Finally, let's add both bars' weights and we'll get the answer:

`(4)/(1) + (12)/(5) = (4 * 5)/(5) + (12)/(5) = (20 + 12)/(5) = (32)/(5) = 6.4`
