Step-by-step explanation:
ratio of W : L = 3:7
Add the ratio which is 10.
7/10= 42
how about 3/10?
Therefore 3/10*42*10/7 = 18
The width of painting is 18 inches
Solution:
Given that,
The Ratio Of The Width To The Length Of A Painting Is 3 To 7
Which means,
width : length = 3 : 7
Let the width be 3x
Let the length be 7x
Given,
The Painting Is 42 In. Long
length = 42
7x = 42
x = 6
Then,
Width = 3x = 3(6) = 18
Thus width of painting is 18 inches
