Antonio makes only one size of latte, and he uses 1/3 cup of milk in each drink. How many lattes can Antonio make with 7/9 cups of milk?


Sagot :

[tex]\frac{1}{3}\ cup\ of\ milk\ for\ 1\ drink\\ \frac{7}{9}\ cup\ of\ milk\ for\ x\drinks\\\\ making\ proportion:\\ \frac{1}{3}-1\\ \frac{7}{9}-x\\\\ cross\ multiplication\\\\ \frac{1}{3}x=\frac{7}{9}\ \ \ \ multiply\ by\ 3\\\\ x=\frac{7}{3}=2\frac{1}{3}\\\\ Antonio\ can\ make\ 2\ lattes. [/tex]
