Answer:
The average weight of new born otter was, [tex]1\frac{31}{40}[/tex]
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
"[tex]\frac{9}{10}[/tex] kg less than average weight of a new born otter" means [tex]x-\frac{9}{10}[/tex]
As per the given information, we have;
[tex]\frac{7}{8} = x -\frac{9}{10}[/tex]
Add [tex]\frac{9}{10}[/tex] both sides, we have;
[tex]\frac{7}{8} + \frac{9}{10} = x[/tex]
Take LCM of 8 and 10 is, 40
⇒[tex]\frac{35+36}{40}=x[/tex]
Simplify:
[tex]x = \frac{71}{40} = 1\frac{31}{40}[/tex]
Therefore, the average weight of new born otter was, [tex]1\frac{31}{40}[/tex]
