Question

I spent 3/4 of my money, and then I spent 1/5 of what was left. What part of all the money do I have left?

Answer 1

The part of all the money I have left
`\large\bf \implies{ (1)/(5)}`

Explanation:

Given that

`\bf \longrightarrow(1 - (3)/(4) ) * (1 - (1)/(5) ) \\ \\ \bf \longrightarrow (4 * 1 - 1 * 3)/(4) * (5 * 1 - 1 * 1)/(5) \\ \\ \bf \longrightarrow (4 - 3)/(4) * (5 - 1)/(5) \\ \\ \bf \longrightarrow (1)/(4) * (4)/(5) \\ \\ \bf \longrightarrow\frac{ \cancel4}{ \cancel{20} } \\ \\ \bf \longrightarrow(1)/(5)`
