Question

Mama a cumparat de la piata 1/2 kg de cartofi, 3/4 kg ceapa si 1 1/2 kg de rosii! Cantaresc legumele cumparate 5 kg?

Answer 1

500g[cartofi]+750g[ceapa]+1kg+0,5kg[rosii]
⇒500g[cartofi]+750g[ceapa]+1,5kg[rosii]
⇒2750g[legume-total]
⇒2750g=2,75kg unde 2,75kg≠5kg;
⇒legumele cumparate nu cantaresc 5 kg;

Answer 2

$\frac{1}{2} + \frac{3}{4} + 1\frac{1}{2} = \frac{2+3+6}{4} = \frac{11}{4} \\ \\ \frac{11}{4} = 2 \frac{3}{4}$
