Question

What is 2 2/5 + 1/15

Answer 1

Question

What is

`2(2)/(5)+(1)/(15)`

Answer:

Note that

`2(2)/(5)`

Is a mixed fraction, meaning 2 units plus 1/5. First, lets convert that to a normal fraction, knowing that

`a(b)/(c)=(a* c+b)/(c)`

Where a, b and c are any number. Therefore,

`2(2)/(5)=(2*5+2)/(5)\rightarrow(10+2)/(5)\rightarrow(12)/(5)`

Thus,

`\begin{gathered} 2(2)/(5)+(1)/(15)=(12)/(5)+(1)/(15) \\ \text{Operate using LCM (15)} \\ (12*3)/(15)+(1)/(15)=(36+1)/(15) \\ \rightarrow(37)/(15) \\ \end{gathered}`

So

`2(2)/(5)+(1)/(15)=(37)/(15)`
