84/132 =7/11 (divide top and bottom by 12)
84/264 = 42/132 = 21/66 = 7/22
Sue has Z. Marcia has (3Z - 84), three times as much as Sue, minus 84. Together their amounts equal 132. So, The amount Sue has plus the amount Marcia has is 132 or, Z + (3Z - 84) = 132 Then, Z + 3Z = 132 + 84 (minus 84 from one side of the expression, and add it to the other side) Z + 3Z = 216 (Z + 3Z)/Z = 216/Z (divide both sides by Z to get one Z on one side) Z/Z + 3Z/Z = 216/Z (or written like this) 1 + 3 = 216/Z 4 = 216/Z 4 x Z = (216/Z) x Z (multiply both sides by Z) 4Z = 216 4Z/4 = 216/4 (divide by 4 to isolate Z) Z = 54 So, Sue has 54, therefore if Marcia has (3Z - 84), then 3 x 54 - 84, which is 78. So, Marcia has 78 We can check that together, 54 plus 78 equals 132.
The GCF is 12.
12 is the highest common factor of 36, 84, and 132.
