Given:
Drawing dimension:
12 inches by 9 inches
Determine how wide will the drawing be if it was reduced to 8 inches long.
Solution:
In order to determine the measurement of the width of the drawing, we refer to the given inches and its ratio.
12:9 can be divided into 3, to take the original ratio,
12:9 = 4:3
Since the length of the new drawing is 8 inches, which is two times 4, in order to determine the width we multiply 3 by 2.
= (3)(2)
=6 inches
Final answer:
The width of the drawing is 6 inches long.
