2d + 1 fifth
2d + 1/5
Sorry I forgot to put in the answer.
It's 2d +1/5 = 3/5
2d +1/5 = 3/5
2d + 1/5 - 1/5 = 3/5 - 1/5
2d = 2/5
d = (2/5)/ 2
d = (2/5) * 1/2
d = 2/10 = 1/5
To find the sum of 2d and 1 fifth, we need to clarify what "1 fifth" means in mathematical terms.
"1 fifth" refers to one part out of a total of five equal parts. In other words, it is the fraction 1/5.
Now, to simplify the expression, 2d + 1/5, we need a common denominator. The least common denominator (LCD) for the expression is 5, as it is the denominator of the fraction.
To make the expression have a common denominator of 5, we need to convert 2d into a fraction with 5 as the denominator. This can be done by multiplying 2d by 5/5: (2d * 5/5) + 1/5.
Multiplying 2d by 5/5, we get 10d/5. Therefore, the simplified expression becomes: (10d/5) + 1/5.
Now that we have the expression with a common denominator, we can combine the like terms. The numerators will be added together while the denominator remains the same.
(10d/5) + 1/5 can be written as (10d + 1)/5.
So, the sum of 2d and 1 fifth is (10d + 1)/5.
