Question

Calcule quantos quilogramas há em : A) 3/8 de 2 t B) 2/5 de 2 t C) 1/20 de 2 t D)10/25 de 2 t E) 6/10 de 2 t F) 2/40 de 2 t

Answer 1

a) 3/8 de t = 3/8 de 1000 kg = 1000/8 kg = 125 km
b) 2/5 de 2t = 1/5 de 2000 = 2000/5 = 400 kg
c) 1/20 de 2t = 1/20 de 2000 = 2000/20 = 100 kg
d) 10/25 de 2t = 2/5 de 2000 = 4000/5 = 800 kg
e) 6/10 de 2t = 6/10 de 2000 = 6x2000/10 = 6x200 = 1200 kg
f) 2/40 de 2t = 1/20 de 2000 = 2000/20 = 200/2 = 100 kg
