Ronald draws a blueprint of his house. he uses a scale 1/2 centimeter equals 3/4 foot on the actual house. how many centimeters on the blueprint are equivalent to 1 foot on the actual house?

For this question you have:
1/2 centimeter = 3/4 foot 
so you can say:
1/2*2  centimeter = 3/4 *2 foot 
so you will have:
1 centimeter = 3/2 foot or 1.5 foot :
i hope this is helpful 
have a nice day
