according \: to \: the \: question \\ let \: the \: number \: be \: x \\ now \: given \\  \frac{3}{5} of \: a \: number \: ( x) = 4 +  \frac{1}{2}  \\  =  \frac{3}{5}  \times x =  \frac{8 + 1}{2}  \\  =  \frac{3}{5} x =  \frac{9}{2}  \\ now \: cross \: multiplication \:  \\  = 3x \times 2 = 9 \times 5 \\  \\  = 6x = 45 \\  = x =  \frac{45}{6}  \\  = x =  \frac{15}{2} \:  or \: 7.5 \\

Therefore the answer is 7.5
