A baby otter was born 3
4
of a month early. At birth, its weight was
7
8
kilograms,
which is 9
10
kilogram less than the average weight of newborn otter in the
aquarium. What is the average weight of newborn otter?

Step-by-step explanation:
Let average weight of new born otter be x.
As per the given statement: At birth it's weight was 7/8 kilograms which is 9/10 kilogram less than the average weight of a new born otter in the aquarium
"\frac{9}{10}
10
9
kg less than average weight of a new born otter" means x-\frac{9}{10}x−
10
9
As per the given information, we have;
\frac{7}{8} = x -\frac{9}{10}
8
7
=x−
10
9
Add \frac{9}{10}
10
9
both sides, we have;
\frac{7}{8} + \frac{9}{10} = x

=x
Take LCM of 8 and 10 is, 40
⇒\frac{35+36}{40}=x
40
35+36
=x
Simplify:
x = \frac{71}{40} = 1\frac{31}{40}x=
40
71
=1

Therefore, the average weight of new born otter was, 1\frac{31}{40}1
