Answer:
4 (as in 25/4)
Step-by-step explanation:
Write and solve an equation of ratios:
x 15
------ = ------
10 24
Then 24x = 150, and x = 150/24 = 6.25. This is equivalent to 25/4.
Answer:
x = 25/4
Step-by-step explanation:
If the rectangles are similar, the ratio of the side lengths have to be similar
10 24
------ = --------
x 15
Using cross products
10*15 = 24*x
150=24x
Divide each side by 24
150/24=24x/24
150/24=x
Divide the top and bottom by 6
25/4 = x
