Answer 1

Hello Bro !

I am here to help you out !

Comparing means to take ratio and that's all is a piece of cake !

$\huge \pink \bigstar \: \: \green{ \dfrac{ \sf{mass \: of \: electron}} \red{ \sf{mass \: of \: proton}} } \\ \\ = \: \dfrac{9.11 × 10^{-31}}{1.673 × 10^{-21}} \\ \\ = \dfrac{9.11 \times {10}^{ - 31 - ( - 21)} }{1.673} \\ \\ = \dfrac{9.11 \times {10}^{ - 10} }{1.673} \\ \\ = \: \blue{\boxed{ \purple{ \underline{{\orange{ \bf{5.4 \: \times \: {10}^{ - 10} }}}}}}}$
