If 2 sweaters cost 27.04. How much would 6 sweaters cost. 81.12 right?
You have written your equations backward.
27.04/ 2 = X/ 6
Multiply both sides by 2
X = 27.04 * 3 = 81.12
This is a ridiculous mistake that everyone makes.
1/4 equals 4. Because get too much involved in procedure that they loose common sense.
