Direct Proportion Between Number of Bars and Mass
Secondary 2
The table below shows the number of chocolate bars, \(n\), and the corresponding mass of
the bars, \(M\)grams.
| \(M\)(grams) | \(60\) | \(120\) | \(180\) | \(240\) | \(300\) |
|---|---|---|---|---|---|
| \(n\) | \(5\) | \(10\) | \(15\) | \(20\) | \(25\) |
- Show that \(M\) and \(n\) are in direct proportion.
- Write down an equation connecting \(M\)and \(n\).
- Find the value of \(n\) when the total mass of the bars is \(480\) grams.
