Answer 1

GIVEN :-

• wieght of baby = 2.7 kg

TO FIND :-

• wieght of baby in pounds

SOLUTION :-

so , as we know according to conversion of wieght :-

$\implies \boxed{ \rm{1 \: kg = 2.20 \: pounds}}$

[ note : it's approx value ]

hence ,

$\implies \rm{2.7 \: kg =( 2.7 \times 2.20) pounds}$

$\implies \rm{2.7 \: kg =5.94 \: pounds}$

hence we conclude that ,

$\implies \boxed{ \boxed{\rm{weight \: of \: baby \: = 5.94 \: lb}}}$
