Convert 96.5 decaliters to hectoliters. 0.965 hectoliters 9.65 hectoliters 965 hectoliters 9,650 hectoliters
SIZIF [17.4K]

Answer:

Option B, 9.65 hectoliters

Explanation:

As we know that in one hectoliter there are ten decaliters

1 hectoliter = 10 decaliters

or

1  decaliters = \frac{1}{10} hectoliter

For converting any small unit into a large unit it is to be divided by number of units in large unit.

Thus,

96.5  decaliters  in terms of hectoliter is equal to

\frac{96.5}{10} \\= 9.65

Hence, option B is correct
