3/14 = x/84 Multiply by 84 on both sides: (3/14) x 84 = x x = (3 x 84)/14 = 18
The three are 84, 168, and 252 - the first three multiples of 84 (14 = 2 x 7, 84 = 2 x 2 x 3 x 7) 84 = 1 x 84 , 6 x 14 168 = 2 x 84, 12 x 14 252 = 3 x 84, 18 x 14 (only the sixth multiples of 14)
84 x 84 = 7056
84
2 x 42=84 4 x 21=84 6 x 14=84
3/14 = x /84 Multiply both sides by '84' Hence 3 x 84 / 14 = x or x = 3 x 84/14 Cancel down by '7' x = 3 X 12/2 Cancel down by '2' x = 3 x 6 x = 18 The answer!!!!!
x - 84
14 x 6 = 84
1 x 84, 2 x 42, 3 x 28, 4 x 21, 6 x 14, 7 x 12 = 84
22 x 3 x 7 = 84
2 x 2 x 3 x 7 = 84
1 x 84, 2 x 42, 3 x 28, 4 x 21, 6 x 14, 7 x 12 = 84
