proportion

5. In order to
solve it we
have to
multiply the
means
We have
missing
extremes
The answer will be
divided to the
remaining extreme

8. How about in fraction form?
Don’t panic!! It’s
easy
Just convert it to
this form and same
process

10. How to determine if the ratios are
proportion or not?
Lets have this example
In order to know if it is a proportion we will divide both
MEANS to EXTREMES and EXTREMES TO MEANS their answers
must be the same. If not , therefore it is not a proportion.
42÷7
36÷6

11. 42÷7
36÷6
42÷7 = 6
36÷6 = 6
Their answers are
both the same so
it is a
PROPORTION.
