Add 2 tenth to 1 half

In order to add fractions you need to, if possible, simplify any fractions that are capable of simplifying. 2/10 can be shortened to 1/5, but for this question it may not be necessary, that we can add 1/5 to 1/2.

Find a common denominator of 10 since both of the 2 and 5 go into 10. In order to make it the same meaning you need to change the numerator. Since we timed 2 by 5 to make 10 we must times the same to to top number. 1/5 becomes 2/10 and 1/2 becomes 5/10. Now it is easy to add the 2/10 and 5/10 together. 2+5 = 7

Since you don't add the bottom numbers togetherthe final answer is 7/10
