Question

a photograph measuring 5.5cm by 9cm is enlarged in the ratio of 7 : 5 find the new length and width of the picture?

Answer 1

Step-by-step explanation:

Enlarging in the ratio 7:5 means that you multiply original lengths by (7/5). So 5.5

becomes (7/5)(5.5) = 7.7 and 9 becomes (7/5)(9) = 63/5 = 12.6. So new dimensions

of the picture are 7.7 cm by 12.6 cm. We cannot say which is length or width since

we were not informed which was length or width in the original dimensions.

Answer 2

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
