84 x 97 = 8148
84 times 97 equals 8148
x = 77 x + 20 = 97 x = 97 - 20 x = 77
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)
1 x 97, 97 x 1 = 97
84 x 84 = 7056
84
2 x 42=84 4 x 21=84 6 x 14=84
Long division does a neat job of it.
84 multiplied by 97 is 8,148.
