7. 7x7=49. 7x11=77. 7x12=84.
The GCF is 7.
84 - 7 = 77
To get this answer, you will need to divide both answers by 5 first, because that is the obvious number that will go into both. 385/5= 77 420/5=84 So the new fraction is 77/84. 7 will go into both (it goes into 70, and 70 plus 14(another multiple of 7!) = 84) 77/7=11 84/7=12 385/420 in its simplest form is 11/12!
77
77 + 84 = 161
The greatest common factor of 42, 77 and 84 is 7.
The GCF is 7.
7. 7x7=49. 7x11=77. 7x12=84.
The GCF is 7.
84 - 7 = 77
Their factors are: 77: 1, 7, 11, 77 84: 1, 2, 3, 4, 6, 7, 12, 14, 21, 28, 42, 84
GCF(84, 77, 49) = 7.
To get this answer, you will need to divide both answers by 5 first, because that is the obvious number that will go into both. 385/5= 77 420/5=84 So the new fraction is 77/84. 7 will go into both (it goes into 70, and 70 plus 14(another multiple of 7!) = 84) 77/7=11 84/7=12 385/420 in its simplest form is 11/12!
70, 77, 84, 91 & 98
7 x 10 = 70 7 x 11 = 77 7 x 12 = 84 87 - 84 = 3 12 times with 3 remaining
84 over 77 in lowest terms = 12/11 or 1 1/11
