Equivalent Fractions

2/3 is equivalent to 8/12
This can be shown by multiplying by 2/3 by 4/4
6/15 is equivalent to 2/5
Here we Divide 6/15 by 3/3

The two procedures of Multiplying or Dividing
by the same number TOP and BOTTOM
is useful to REDUCE FRACTIONS
or for ADDING and SUBTRACTING of fractions.

2/9 + 1/9 = 3/9
but 3/9 needs reducing so DIVIDE by 3/3
Thus, 3/9 is equivalent to 1/3

2/3 + 1/4
now we need to Multiply 2/3 by 4/4
and 1/4 is Multiplied by 3/3
Now the orginal problem becomes
8/12 + 3/12 which EQUALS 11/12
