Question

Frank practiced piano for 2 ⅓ hours yesterday. He practiced 1 ⅛ hours today. How long did he practice on both days combined? Convert your answer to hours and minutes.

Answer 1

Answer:
`3 hr and 27 min`

Explanation:

Given

Frank practiced piano for
`2(1)/(3)\ \text{hours}` yesterday and
`1(1)/(8)\ \text{hours}`

In total frank practiced

`\Rightarrow 2(1)/(3)+1(1)/(8)\\\\\Rightarrow (7)/(3)+(9)/(8)\\\\\Rightarrow (7* 8)/(3* 8)+(9* 3)/(8* 3)\\\\\Rightarrow (56+27)/(24)=(83)/(24)\ \text{hours}\\\Rightarrow (83)/(24)\ \text{hours}\ or\ 3\ \text{hours and 27 min 30s}`
