3/7+1/3

Question

as a fraction

Answer 1

To add these fractions, we need to find a common denominator. The least common multiple of 7 and 3 is 21. So, we rewrite the fractions with the denominator of 21:

3/7 = 9/21 (multiply numerator and denominator by 3)
1/3 = 7/21 (multiply numerator and denominator by 7)

Now, we can add the fractions:

9/21 + 7/21 = 16/21

Therefore, 3/7 + 1/3 as a fraction is 16/21.

Answer 2

2/3+3/5
as fraction

Answer 3

To add these fractions, we need to find a common denominator. The least common multiple of 3 and 5 is 15. So, we rewrite the fractions with the denominator of 15:

2/3 = 10/15 (multiply numerator and denominator by 5)
3/5 = 9/15 (multiply numerator and denominator by 3)

Now, we can add the fractions:

10/15 + 9/15 = 19/15

Therefore, 2/3 + 3/5 as a fraction is 19/15. However, this answer is an improper fraction (the numerator is larger than the denominator), so we can simplify it to a mixed number:

19/15 = 1 4/15

So, 2/3 + 3/5 as a fraction is either 19/15 or 1 4/15.
