Question 1133281: Circle C Farm has 1,500 chickens. They separate the chickens into 6 different areas. How many chickens are in each area? Define a variable and write an equation. Solve the equation.
According to my son's Math book, the equation is a multiplication equation, as follows:
Let x = the number of chickens in each area;
6x = 1500; x = 250
Why is this not a division equation even though it says they " separate the chicken into 6 areas". Doesn’t separating the chicken translate to dividing?
Would greatly appreciate your help in understanding what in the word problem would help my son figure out that he needs to write a multiplication equation.
