\(=\dfrac{29}{57}\)
\(=\dfrac{29}{57}\cdot\dfrac{31}{43}+\dfrac{29}{57}\cdot\dfrac{12}{43}=\dfrac{29}{57}\left(\dfrac{31}{43}+\dfrac{12}{13}\right)=\dfrac{29}{57}\)

`29/43 * 31/57 + 29/57 * 12/43`
`= 29/57 * 31/43 + 29/57 * 12/43`
`= 29/57 * (31/43 + 12/43)`
`= 29/57 * 43/43`
`= 29/57 * 1 = 29/57`
