Question

Mr West has a picture that is 4 inches wide and 7

inches long. He wants to enlarge it so that it is 19
inches long How wide should the picture be?​

Answer 1

10 6/7 inches

Explanation:

Ratio (k) = image/pre-image

k= 19/7

4 x 19/7 = 76/7 = 10 6/7

Answer 2

Explanation:

The ratio of new length 7 to the initial length 19 is 2.7

Therefore new width will be 2.7×4 which will be 10.9 or about 11 inches
