2/3 is equivalent to 4/6 (2 x 2 =4, 3 x 2 = 6). 4/6 is 4 days.
54 = 6 x 3 4/2 or 54 = 6 x 3 4-2
12. (6 x 2, 4 x 3 and 3 x 4)
6 / ( x + 4 ) = 2 / 3 1 - Multiply both parts by 3 3 * 6 / ( x + 4 ) = 2 2- Multiply both parts by (x+4) 3 * 6 = 2 * ( x + 4 ) 3 - Simplify 18 = 2x + 8 10 = 2x 5 = x
6 = 2 x 3 4 = 2 x 2 9 = 3 x 3 ⇒ LCM is 2 x 2 x 3 x 3 x 7 = 252
36/2=18 18/2=9 9/3=3 36/3=12 12/2=6 6/2=3 36/4=9 9/3=3 36/6=6 6/2=3
