How do you rename a pair of fractions with common denominators?

Updated: 9/18/2023

Example: 7/30 + 5/42
Find the LCD by factoring them.
2 x 3 x 5 = 30
2 x 3 x 7 = 42
2 x 3 x 5 x 7 = 210, the LCD
30 x 7 = 210
42 x 5 = 210
7/30 x 7/7 = 49/210
5/42 x 5/5 = 25/210
49/210 + 25/210 = 74/210
Simplify if necessary.
7/30 + 5/42 = 37/105
