A ratio shows us the number of times a number contains another number. The width of the frame after enlargement is 5 inches.

What is a Ratio?

A ratio shows us the number of times a number contains another number.

Given that the frame is 1 inch wide and 4 inches tall. Now, if the frame is enlarged, then the ratio of the corresponding sides will be equal.

Further, given that height after enlargement is 20 inches. Therefore, if the ratio of the height of the before enlargement and after enlargement is taken, then it will be,

Ratio = After Enlargement/ Before Enlargement

Ratio = 20 inches / 4 inches

Ratio = 5

Now, if we use the ratio to find the width of the frame after enlargement, then the frame width will be,

Ratio = After Enlargement/ Before Enlargement

5 = Width after Enlargement/ Width before Enlargement

5 = Width after Enlargement/ 1 inche

Width after Enlargement = 5 inches

Hence, the width of the frame after enlargement is 5 inches.
