Question

6.5 cm is to be enlarged. If the enlargement of the longest side is 18 cm then the length of smaller side in cm is​

Answer 1

Answer:

The 7:5 or 7/5 isn’t the ratio between the width and height of the photograph. It is actually an increase to such measurements.

Let’s try this: 7/5 = 1.4

This is 40% increase of its dimensions’ measurements.

Thus,

5.5 * 1.4 = 7.7 cm

9 * 1.4 = 12.6 cm

The new width and height will be:

7.7 cm by 12.6 cm

An increase with the photograph’s width and height while retaining their original ratio.

5.5/9 = 7.7/12.6
