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
