The LCM is: 2205
For 49,57: 2793 For 4/9, 5/7: 63
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
41 49 67
LCD(63, 7) = 63.
5/7 + 7/9 = 45/63 + 49/63 = 94/63 or 1 31/63
49/63=0.7...
LCD(9, 21) = 63
The GCF of 49 and 63 is 7. The greatest common factor is the highest number that divides exactly into two or more numbers. 49: 1, 7, 49 63: 1, 3, 7, 9, 21, 63
9 by 5- 3 by 3 by 5 9 by 7 - 3 by 3 by 7 7 by 7. you need to go to The Tutoring Center, I used to work there, Lowest Common Denominators are in the first few pages of their workbooks. The LCD for those three numbers is one. They don't share any other factors
45 percent of 63 = 28.3545% of 63= 45% * 63= 0.45 * 63= 28.35
The LCD is 9.
