Question

73 9/12 ÷ 6 2/5A. about 5B. about 8C. about 12D. about 15

Answer 1

Converting both into improper fractions:

`\begin{gathered} 73(9)/(12)/6(2)/(5) \\ \\ \rightarrow(876+9)/(12)/(30+2)/(5) \\ \\ \rightarrow(885)/(12)/(32)/(5) \end{gathered}`

Simplifying,

`\begin{gathered} (885)/(12)/(32)/(5) \\ \\ \rightarrow(295)/(4)/(32)/(5) \end{gathered}`

Remember that in order to divide two fractions, we cross-multiply:

`(295)/(4)/(32)/(5)\rightarrow(295\cdot5)/(32\cdot4)\rightarrow(1475)/(128)\rightarrow11.5234\ldots`

Which is about 12
