Question

A rectangular photo with dimensions of 1.5 inches wide by 2 inches long is enlarged to a length of 8 inches. What is the width of the enlarged print?

Answer 1

Step-by-step explanation:

Given length = 2 inches

Width = 1.5 = 3/2

Ratio of the dimensions =2:3/2= 4:3

Given lenght is enlarged to 8 & let width =x

i. e 4:3::8:x

We know that

product of extremes = product of means

4x = 8×3

4x = 24

x =24/4=7

Therefore

the width should be enlarged to 7 inches

Hope this is help full

Answer 2

Answer:

The width of the enlarged print is 6 inches.

Step-by-step explanation:

Given dimensions are:

Length = 2 inches

Width = 1.5 inches

Ratio of length and width is = 2 : 1.5

                                              = 4 : 3

Now, enlarged length = 8 inches

Let, enlarged width = x inches

The ratio of enlarged length and width will be same as the ratio of original length and width.

Then, 8 : x :: 4 : 3

         8/x = 4/3

         x = 8*3/4

         x = 6

Thus, the enlarged width is 6 inches.
