Question

intr-o sticluta erau 20 cl de sirop.un copil ia de 3 ori pe zi cate 5 ml de sirop . ce cantitate de sirop ramane in sticluta dupa o saptamana

Answer 1

$3 \times 5 \:ml= 15 \: ml = 1.5 \: cl\:(pe \:zi)$

$7 \times 1.5 \:cl= 10.5 \: cl\:(pe \: saptamana)$

$20 \: cl - 10.5 \: cl = 9.5 \: cl\:(cantitatea \: ramasa)$
