Answer:
The smaller bottle holds 12.5 ml of perfume.
====================
<h2>Given</h2>- Two bottles of similar shape;
- Larger bottle has volume of 100 ml;
- The length of larger bottle is 10 cm;
- The length of smaller bottle is 5 cm.
- The volume of smaller bottle.
Find the scale factor, the ratio of corresponding dimensions:

Substitute the known values and find the volume of small bottle:
The smaller bottle holds 12.5 ml of perfume.
