Natural sonlar va ular ustida amallar bo‘yicha savol
Javob va yechimni ko‘rish
Javob: 109
Ifodaning ichidagi amalni avval bajarish kerak, chunki qavs ichidagi har qanday amal boshqa barcha amallardan oldin hisoblanadi.
Birinchi qadam: $6:2=3$, shunda $9-6:2=9-3=6$.
Keyingi qadam: $12\cdot(9-6:2)=12\cdot6=72$.
Endi qolgan ikki amalni bajarish: $111:3=37$, shunda $37+72=109$.
Javob $109$, ya’ni variant **B**.
