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
[tex]\frac{3*3}{7*3} +\frac{1*7}{3*7}[/tex]
3) Simplify. Denominators are now the same.
[tex]\frac{9}{21} +\frac{7}{21} \\[/tex]
4) Join the denominators
[tex]\frac{9+7}{21}[/tex]
5) Simplify
[tex]\frac{16}{21}[/tex]
Answer:
[tex]{ \tt{ \frac{3}{7} + \frac{1}{3} }} \\ \\ = { \tt{ \frac{(3 \times 3) + (7 \times 1)}{21} }} \\ \\ = { \tt{ \frac{9 + 7}{21} }} \\ \\ = \: \dashrightarrow \: { \tt{ \frac{16}{21} }}[/tex]
