The LCM is: 2205
For 49,57: 2793 For 4/9, 5/7: 63
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
45 percent of 63 = 28.3545% of 63= 45% * 63= 0.45 * 63= 28.35
The LCD is 9.
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
49 x 2 = 98 14 x 7 = 98 98 is the LCD
