Question

a length originally 6cm, is increased so that the ratio of the new length to the old is length is 9:2. what is the new length?

Answer 1

Answer:

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

0.6111111
