Two rectangles have equal areas. If the base and altitude of one are 12mm and 8mm, and the base of the other is 16mm, what is the altitude of the second rectangle?

6mm

Explanation:

since the area of both rectangle is equal, therefore :

Arectangle 1= Arectangle 2

base 1*altitude 1 =base 2*altitude 2

12mm*8mm = 16mm* altitude 2

96mm²= 16mm* altitude 2

96mm²/16mm = altitude 2

6mm = altitude 2

only 10/60 isn't equivalent

hope this : )

sinn is the total amount of students now and m were the students before, you subtract them both (n-m) and divide that by m. then, since to get a percentage from a fraction you have to multiply by 100, your answer should look like this: n-m/m*100
