Resposta:

olha aí

Explicação passo-a-passo:

a)

\sf \dfrac{2}{5}\cdot60=\dfrac{120}{5}=2452⋅60=5120=24

b)

\sf \dfrac{1}{5}\cdot(2\times60)=\dfrac{1}{5}\cdot120=\dfrac{120}{5}=2451⋅(2×60)=51⋅120=5120=24

c)

\sf \left(\dfrac{1}{5}\cdot60\right)\times2=\dfrac{60}{5}\times2=\dfrac{120}{5}=24(51⋅60)×2=560×2=5120=24
