Step-by-step explanation:
To add two fractions they must be over a common denominator, which for this problem is
10
.
To put each fraction over a common denominator we must multiply each fraction by the appropriate form of
1
:
2
5
+
1
2
⇒
(
2
2
×
2
5
)
+
(
5
5
×
1
2
)
⇒
4
10
+
5
10
We can now add the numerators of the two fractions over the common denominator:
4
10
+
5
10
⇒
4
+
5
10
⇒
9
