To add these fractions, we need to find a common denominator.
The least common multiple of 15, 21 is 105.
So, we rewrite the fractions with a common denominator of 105:
(5/21) (5/5) = 25/105(2/15) (7/7) = 14/105(2/21)
Now, we add the fractions together:
25/105 + 14/105 + 2/21
= 41/105 + 2/21
To add these two fractions, we need to find a common denominator.
The least common multiple of 21, 105 is 105.
(41/105) + (10/105)
Now, we can add the fractions together:
41/105 + 10/105= 51/105
Therefore, the result is 51/105.
To add these fractions, we need to find a common denominator.
The least common multiple of 15, 21 is 105.
So, we rewrite the fractions with a common denominator of 105:
(5/21) (5/5) = 25/105
(2/15) (7/7) = 14/105
(2/21)
Now, we add the fractions together:
25/105 + 14/105 + 2/21
= 41/105 + 2/21
To add these two fractions, we need to find a common denominator.
The least common multiple of 21, 105 is 105.
So, we rewrite the fractions with a common denominator of 105:
(41/105) + (10/105)
Now, we can add the fractions together:
41/105 + 10/105
= 51/105
Therefore, the result is 51/105.
