Answer:
I will show step by step how to solve these problems.
I recommend getting a whiteboard, it makes these easier.
Explanation:
I have included a picture on how to layout the problem so write it as show
Your percent aka 30 goes on the left top.
you will always put 100 on the left bottom
The part that says on, 47.50 goes on the bottom right
the part that says is goes on the right top, in this case we don't know is, so that is our variable x.
Now we cross multiply. write down 100 x somewhere and then multiply 30 by 47.50.
now we bring down 1425.
divide each by 100. 100/100 cancels it out so now write x =
1425/100 = 14.25
x = 14.25
It is hard to understand this concept at first but it should click soon! comment if you need any help and have a great day.
