Explanation:
Step 1: You have to Multiply the
3
and the
2
together and then add the
1
and that would all be over
3
. Then you get
2
1
3
=
2
×
3
+
1
3
=
7

Step 2: You do the same thing which is
2
times
1
and then add
1
and that would be all over
2
. Then you get
1
1
2
=
1
×
2
+

=

Step 3: Combine together as
7

Next, you have to have a common denominator of
6
.
7
3
times
2
both top and bottom. Then
3
2
is going to be times
3
both top and bottom.
