Answer:
16/21
Step-by-step explanation:
1) Find the least common denominator (LCD) of 3/7,1/3. In other words, find the Least Common Multiple (LCM) of 7,3.
LCD=21
2) Make the denominators the same as the LCD
![\frac{3*3}{7*3} +\frac{1*7}{3*7}](https://tex.z-dn.net/?f=%5Cfrac%7B3%2A3%7D%7B7%2A3%7D%20%2B%5Cfrac%7B1%2A7%7D%7B3%2A7%7D)
3) Simplify. Denominators are now the same.
![\frac{9}{21} +\frac{7}{21} \\](https://tex.z-dn.net/?f=%5Cfrac%7B9%7D%7B21%7D%20%2B%5Cfrac%7B7%7D%7B21%7D%20%5C%5C)
4) Join the denominators
![\frac{9+7}{21}](https://tex.z-dn.net/?f=%5Cfrac%7B9%2B7%7D%7B21%7D)
5) Simplify
![\frac{16}{21}](https://tex.z-dn.net/?f=%5Cfrac%7B16%7D%7B21%7D)
Answer:
Delta = |a b d; b c f; d f g|
(2)
J = |a b; b c|
(3)
I = a+c
(4)
K = |a d; d g|+|c f; f g|.
