3/7 + 3/14, we first need to get both of the denominators equaled. To do this we need to get 3/7 to something over 14. We can do this by multiplying the fraction 3/7 by 2/2.
3/7(2/2) + 3/14
6/14 + 3/14 = 9/14
So 3/7 + 3/14 = 9/14
7 sevenths
3 and 2/7
3/7 + 2/7 = 5/7
13 and 3/7
3/7 + 4/7 = 7/7 = 1
28/63
The easiest way to divide by a fraction is to multiply by the reciprocal. The original problem becomes 9/14 x 7/3 = 63/42 = 3/2 = 1 and 1/2
8 3/7 + 5 5/7 = 13 8/7 = 14 1/7
3/5 plus 3/7 = 36/35 or 1 and 1/35
Three sevenths plus six sevenths equals nine sevenths. To add fractions with the same denominator, you simply add the numerators together and keep the denominator the same. In this case, 3 + 6 = 9, so the sum is 9/7.
There are 3*7 plus 2 = 23 days
