Introduction

Typical problem: You need to divide a total between two people (with no leftovers). The first person should receive an amount proportional to the value x, and the second person should receive an amount proportional to the value y. So, how much should each person receive?

`\text{TOTAL = Person 1 + Person 2}`

`\frac{\text{Person 1}}{x}=\frac{\text{Person 2}}{y}`
The total TO BE DIVIDED IS .
Person 1 should receive PROPORTIONAL TO THE VALUE
Person 2 should receive PROPORTIONAL TO THE VALUE
Person 1 will receive
Person 2 will receive

Introduction

Typical problem: You need to divide a total among three people (with no leftovers). The first person should receive an amount proportional to the value x, the second person proportional to the value y, and the third person proportional to the value z. So, how much should each person receive?

`\text{TOTAL = Person 1 + Person 2 + Person 3}`

`\frac{\text{Person 1}}{x}=\frac{\text{Person 2}}{y}=\frac{\text{Person 3}}{z}`
The total TO BE DIVIDED IS .
Person 1 should receive PROPORTIONAL TO THE VALUE
Person 2 should receive PROPORTIONAL TO THE VALUE
Person 3 should receive PROPORTIONAL TO THE VALUE
Person 1 will receive
Person 2 will receive
Person 3 will receive
