\mathsf{Let , \: the \: fourth \: proportion \: be \: d}

\mathsf\red{Given}

\mathsf{ 4.8 : 1.6 :: 5.4 : d}

\mathsf \red{we \: know \: that \:  :  } \mathsf{ \frac{a}{b}  =  \frac{c}{d} } \\ \\   \mathsf{a  = 4.8 \: ,  \: b \: =1.6 \:,c = 5.4   } \\  \\  \mathsf \red{by \: substituting \: in \: above \: formula :} \\ \\   \mathsf{ \frac{4.8}{1.6}  =  \frac{5.4}{d} } \\  \\ \mathsf{d \:  =  \:  \frac{5.4 \times 1.6}{4.8} } \\  \\   \boxed{\mathsf{d \:  =  \: 1.8}} \\  \\  \mathsf \red{ \therefore \: fourth \: proportion \: will \: be \: 1.8}
