Question

a cake weighing 2560kg was cut into smaller pieces each weighing 640g.how many small pieces of cakes were there​

Answer 1

• 640g=0.640g

Mass of car=2560kg

Total small pieces:-

$\\ \sf\longmapsto \dfrac{2560}{0640}$

$\\ \sf\longmapsto 4000$

Answer 2

Answer:

$total \: weight \: of \: cake = 2560 kg\\weight \: of \: one \: piece \: = 640g = .640kg \\ cut \: in \: to \: n \: small \: pieces \\ so \: \frac{2560}{cut \: in \: to \: n \: pieces \: } = .640(mass \: of \: one \: piece) \\ \frac{2560}{n} = .640 \\ \frac{2560}{.640} = n \\ 4000 = n \\ therefore \: total \: number \: of \: piece = 4000 \\ thank \: you$
