Adding 79 to 321 gives 400 as the result(79+321).
3/7=9/21 1/3=7/21 9+7=16/21
21 + 9 + 7 = 37
3 over 7 because nothing can get to 2 when your dividing by 9 plus 9/3=3 and 21/3=7 ( / = division)
9+7+5+3+1 16+5+3+1 21+3+1 24+1 25
If Z = 3, then (9 + 7Z) = [ 9 + 7(3) ] = 9 + 21 = 30
3/7 + 8/21 = 9/21 + 8/21 = 17/21
14/21 + 9/21 = 23/21
Are you trying to say 17 + 6 + (7-9) ? = 21
21
1 + 2 = 3 + 3= 6 + 4 = 10 + 5 = 15 + 6 = 21 +7 = 28 + 8 = 36 + 9 = 45
The factors of 9 are: 1, 3, 9 The factors of 21 are: 1, 3, 7, 21
7/20 + 3/9 = 7/20 + 1/3 = 21/60 + 20/60 = 41/60
