Given the statement:
Kelli has a family photograph with a width of 6 in and a height of 8 in.
Determine the height of the photograph if she wants to increase the width by 15in.
Solution:
We can determine the height of the photograph by taking note first of the photograph's proportion. 6 in by 8 can be written as,
=6:8 or 3:4
Since we know that the proportion is 3:4, we divide 15 by 3, then multiply it by 4 in order to determine the height.
= 15/3
= 5
= (5)(4)
= 20in
Final answer:
The height of the photograph is 20 in.
