Elis [28]

Answer:

The dimensions are 24 and 12 meters.

Grade 7 Need help with proportions (PICTURE INCLUDED)
jeka57 [31]
What you are doing with proportions most the time is solving for a variable which in this example I will use an x. You have to do something called cross multiplying. now look at number 21. when you cross multiply you multiply the number of the top part of the fraction on the left side to the bottom part of the fraction on the right side. In that example 1 × 36 = 36. now write 36 = 16x since you have to cross multiply the other parts of the fraction. Then you would divide both sides of the equation by 16. I will make a mixed fraction for this example. 2 4/16 which simplified equals 2 1/4

What is 15% of $32.50 and please explain how you got your answer please
Ann [662]
You can say : 15% ⇒ ? if 100% ⇒ 32.50 $ 
so next you can say : 15/100 = ?/32.50 ⇒ ? = (15/100) × 32.50 = 15 × 32.50 ÷ 100 = 4.875 ⇒ so the answer is 4.785 $ ;D i hope this will be helpful :))
