Answer 1

The average weight of the newborn otter is
`(71)/(40)\ kg.`

Explanation:

Given:

A baby otter was born 3/4 of a month early at first it's weight was 7/8 kg which is 9/10 kg less than the average weight of newborn otter in the aquarium.

Now, to find the average weight of the newborn otter.

Let the average weight of the newborn otter be
`x.`

It's weight was =
`(7)/(8) \ kg.`

It's weight is less than the average weight of newborn by =
`(9)/(10) \ kg.`

According to question:

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

Adding both sides by
`(9)/(10)` we get:

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

`x=(36+35)/(40)`

`x=(71)/(40) \ kg.`

Therefore, the average weight of the newborn otter is
`(71)/(40)\ kg.`
