20/25 = 4/5 is that your question?
No Farther down...It says step 3
itd be simpler if you just typed a question :)
In a horror movie featuring a giant beetle, the beetle appeared to be 50 feet long. However, a model was used for the beetle that was really only 20 inches long. A 30-inch tall model building was also used in the movie. How tall did the building seem in the movie?
it says the answer is 75...I keep coming up with 600
When it goes through the steps to solve it seems to be step 3 where I lose it
20 is to 50 as 30 is to what number...
lets write this like fractions:
-- = --
What do you get from here?
20 x X=30x50
20x = 1500
now how do we solve for x?
divide both sides by 20
very good, you are a pro at this :)
that gives us:
x = 1500/20
TADA!!! excelent job :)
Thanks I was getting hung up on the inches and feet part of it
