This activity will help you understand about the concept of proportion using media. To get succeed in this activity you need to :
1. Focus on the instruction of the activity.
2. Do the complete practices (several problems) until you understand.
3. Write/ record the problems and how to work out in your math book.
4. Pay attention on the explanation of the algebra (the expression of the problem into Math operation)
A proportion is a name we give to a statement that two ratios are equal. It can be written in two ways:
- two equal fractions, a/b = c/d,
- using a colon, a:b = c:d
That is, for the proportion, a:b = c:d , a x d = b x c
e.g. 3 : 2 = 18 : 12 , 3 x 12 = 2 x 18
