1 1/9 + 2 1/3 = 3 4/9 or three and four ninths. Expressed as a decimal, this is equal to 3.4 recurring (that is, 3.4444...)
7a minus 2, if "3a-2" means 3a minus 2. 3a plus 1 and 1-3rd in parenthesis times 3a, if "3a-2" means 3a squared. a plus 3a squared plus 3a = 1-3rd times 3a plus 3a times 3a plus 1 times 3a = 3a plus 1 and 1-3rd in parenthesis times 3a
(2 +1/3rd) + (2/3rds) = 2 + (3/3rds) = 2 + 1 = 3
4/9 + 2/9 + 1/9 = 7/9
2/9 + 1/3 = 2/9 + 3/9 = 5/9
no if 1 plus 1 equals 2 then 2 plus 2 equals 4.
4
1^2 + 1^2 + 1^2 + 1^2 + 1^2 + 1^2 = 1 + 1 + 1 + 1 + 1 + 1 = 5
One plus one is two. It can be expressed mathematically as 1+1 = 2.
It equals 7
1/2 + 1/2 + 1/2 + 1/2 = 2 2 is four halves.
1+1 or 1 plus 1 is equal to 2.
30. 2+3+5=10, 4+6=10, and 2+4+1+1+2=10.
