Question

Evaluate the following expression.7 1/4 * 2^2 + (8 1/2 - 2) ÷ 331 1/660 1/648 1/236 5/6

Answer 1

We have to evaluate:

`7(1)/(4)\cdot2^2+(8(1)/(2)-2)/3`

We then can write:

`\begin{gathered} 7(1)/(4)\cdot2^2+(8(1)/(2)-2)/3 \\ 7(1)/(4)\cdot4+(6(1)/(2))/3 \\ (7\cdot4+(1)/(4)\cdot4)+((6)/(3)+(1)/(2\cdot3)) \\ (28+1)+(2+(1)/(6)) \\ (28+1+2)+(1)/(6) \\ 31+(1)/(6) \\ 31(1)/(6) \end{gathered}`

Answer: 31 1/6
