Question

2 1/3
11
3/8
2 2/3

Answer 1

To find the scale factor, we need to compare the lengths of the sides in the original object to the lengths of the sides in the photograph.

The original object has sides that each measure 3 cm.
The photograph shows sides that each measure 8 cm.

To find the scale factor, we can divide the length of each side in the photograph by the length of the corresponding side in the original object.

(8 cm) / (3 cm) = 2 2/3

Therefore, the scale factor Leo used to create the photograph from the original is 2 2/3.
