We have that for 2 dozen muffins, we need 600g of flor. We also know that each dozen has 12 muffins, then we have the following relation:
[tex]24\text{ muffins }\rightarrow600g[/tex]To find out how many muffins we can make with 900g of flour, we can use a rule of three:
[tex]\begin{gathered} 24\text{ muffins}\rightarrow600g \\ x\text{ muffins}\rightarrow900g \\ \Rightarrow x=\frac{900\cdot24}{600}=\frac{21600}{600}=36 \\ x=36 \end{gathered}[/tex]therefore, with 900g of flour we can make 36 muffins, or 36/12= 3 dozens.
