2/15+1/3=
2/15 + 1/3 = 7/15
To add the fractions 2/15 and 1/3, we need a common denominator. In this case, the common denominator is 15.
To get 15 as the denominator for the second fraction (1/3), we need to multiply both the numerator and denominator by 5:
1/3 = (1 * 5) / (3 * 5) = 5/15
Now we can add the two fractions with the same denominator:
2/15 + 5/15 = (2 + 5) / 15 = 7/15
Therefore, the simplified fraction is 7/15.
To add fractions, you need to find a common denominator. The common denominator is the smallest multiple that both denominators can divide into evenly.
In this case, the denominators are 15 and 3. The smallest multiple that both 15 and 3 can divide into evenly is 15.
Next, you need to rewrite both fractions so that they have the common denominator of 15.
2/15 can be rewritten as 2 * (1/15).
1/3 can be rewritten as 1 * (5/15), because 3 multiplied by 5 equals 15.
Now that both fractions have the same denominator, you can add them together:
(2 * 1/15) + (1 * 5/15) = 2/15 + 5/15
Combine the numerators (2+5) and keep the denominator the same:
7/15
So, the sum of 2/15 and 1/3 is 7/15.
