It is so very simple and quick to get the answer if you use the calculator that comes with your computer. But since you are not able to do so, the answer is 25.
2 and a half plus 2 and a half plus 10 plus 10 = 25
9/10
1/5 plus 1/2 is the same as 2/10 plus 5/10 = 7/10
11/106 tenths plus one half:= 6/10 + 1/2= (6 + 5)/10= 11/10
42 (half of 80 is 40 and 10% of 20 is 2, therefore 40 + 2)
2 and a half plus 3 and a half plus 4 and a half = 10.5
1/2 + 2/5 = 5/10 + 4/10 = 9/10 :)
1/2 + 1/2 + 1/2 + 1/2 = 2 2 is four halves.
9/10 + ½ =9/10 + 2/10 = 11/10 = 1⅒
It is: 1 and a 1/2 plus 3/5 = 2 and 1/10 or 2.1
5 and a 1/2 plus 4 and 2/3 = 10 and 1/6
It is: 1/2+1/5 = 7/10
