Question

Ana si Maria culeg din livada cirese si umplu 3 ladite a cate 1 kg,2 ladite a cate 1/2 kg si 4 ladite a 1/4 kg fiecare, cate kg de cirese au cules?

Answer 1

Răspuns:

Explicație pas cu pas:

1 kg = 1 × 1000 g = 1000 g

1/2 kg = 1/2 × 1000 g = 1/1 × 500 g = 500 g

1/4 kg = 1/4 × 1000 g = 1/1 × 250 g = 250 g

3 × 1000 g + 2 × 500 g + 4 × 250 g =

3000 g + 1000 g + 1000 g =

4000 g + 1000 g = 5000 g ( total )

5000 g = 5000 : 1000 kg = 5 kg ( total )

Answer 2

3 × 1 kg + 2 × 1 / 2 kg + 4 × 1 / 4 kg =

3 kg + 2 × 0, 5 kg + 4 × 0, 25 kg =

3 kg + 1 kg + 1 kg =

4 kg + 1 kg = 5 kg de cireşe au cules Ana şi Maria
