Question

care este al doilea mod de a rezolva calculul: 72000:5+72000:10+72000:15=
pls ajutati-ma poate dau coroana!

Answer 1

Folosești factorul comun:

72000($\frac{1}{5}$+ $\frac{1}{10}$+ $\frac{1}{15}$)

72000($\frac{6+3+2}{30}$)=72000·$\frac{11}{30}$=2400·11=26400

Sper să te ajute! ^_^

Answer 2

Modul 1
72000:5+72000:10+72000:15=14400+7200+4800=26400

Modul 2
72000:5+72000:10+72000:15=
72000x(1/5+1/10+1/15)=
=72000x(6/30+3/30+2/30)=
=72000x11/30=
=2400x11=
=26400
