a)

Dzielenie możemy wykonywać po kawałku.

$\underset{40+8}{\underbrace{48}}:2=40:2+8:2=20+4=24$

---

$\underset{90+6}{\underbrace{96}}:3=90:3+6:3=30+2=32$

---

$\underset{50+15}{\underbrace{65}}:5=50:5+15:5=10+3=13$

---

$\underset{30+30}{\underbrace{60}}:15=30:15+30:15=2+2=4$

---

---

b)

$240:8=30$

---

$360:9=40$

---

$180:6=30$

---

$\underset{100+100}{\underbrace{200}}:25=100:25+100:25=4+4=8$

---

---

c)

W dzielnej i w dzielniku możemy skreślić na końcu po tyle samo zer.

$36\cancel{0}:1\cancel{0}=36$

---

$27\cancel{0}\cancel{0}:1\cancel{0}\cancel{0}=27$

---

$4800\cancel{0}:1\cancel{0}=4800$

---

$6600\cancel{0}\cancel{0}:1\cancel{0}\cancel{0}=6600$

---

---

d)

$80\cancel{0}:2\cancel{0}=40$

---

$24\cancel{0}\cancel{0}:6\cancel{0}\cancel{0}=4$

---

$120\cancel{0}:4\cancel{0}=30$

---

$300\cancel{0}\cancel{0}:6\cancel{0}\cancel{0}=50$
