the LCD of 5 and 7 is explanation: 7: 14, 21, 28, 35, 42, 49, 56, 63, 70 5: 5, 10, 15, 20, 25, 30, 35, 40, 45, 50 so the LCD is 5 and7 is 35
35
The least common denominator is 14. Whenever there are two values, and one is a multiple of the other, the multiple (larger number) is the LCD.
The LCD for 7 and 5 is 35
14
The lowest common multiple of 7 and 5 is: 35Multiples of 5: 5, 10, 15, 20, 25, 30, 35 ...Multiples of 7: 7, 14, 21, 28, 35 ...
15
It is: 28
42
The factors of 35 are 1, 5, 7, and 35. The factors of 14 are 1, 2, 7, and 14. The common factors of 35 and 14 are 1 and 7, and the GCF is 7.
49 x 2 = 98 14 x 7 = 98 98 is the LCD
from 14/35 divide both sides by 7 14/7 = 2 35/7 = 5 Answer: 2/5
