Answer 1

Answer :
`(71)/(40)` kilograms or 1.775 kilograms

Explanation:

1. You know that:

- The weight of the baby otter was 7/8 kilograms.

- The weight of that baby otter is 9/10 kilogram less than the average weight of a newborn otter in the aquarium.

2. Keeping on mind the information given, let's call the average weight of a newborn otter x. Then, you can write the following expresion:

`x-(9)/(10)=(7)/(8)`

3. Solve for x. Then, you obtain the following result:

`x=(7)/(8)+(9)/(10)\\x=(71)/(40)`

4. Thefore, the answer is
`(71)/(40)` kilograms or 1.775 kilograms.
