Răspuns:
a) 3/2 ÷ 3/5 =
= 2/3 × 5/3
= 10/9
b) 2/7 ÷ 3/2 =
= 7/2 × 2/3
= 14/6
c) 5/8 ÷ 4/15=
= 8/5 × 15/4
= 120/20
d) 5/6 ÷ 5/2=
= 6/5 × 2/5
= 12/25
e) 12/5 ÷ 3/8=
= 5/12 × 8/3
= 40/36
f) 4/25 ÷ 16/15=
= 25/4 × 15/16
= 375/64
g) 1 2/3 ÷ 5/3=
= 1×3+2/3 ÷ 5/3
= 5/3 ÷ 5/3
= 3/5 ×3/5
= 9/25
h) 2/7 ÷ 1 3/2=
= 2/7 ÷ 1×2+3/2
= 2/7 ÷ 5/2
= 7/2 × 2/5
= 14/4
i) 1 4/11 ÷ 1 3/22=
= 1×11+4/11 ÷ 1×22+3/22
= 15/11 ÷ 25/22
= 11/15 × 22/25
= 242/375
j) 5 ÷ 3/4=
= 5/1 ÷ 3/4
= 1/5 × 4/3
= 4/15
k) 2/5 ÷ 4=
= 2/5 ÷ 4/1
= 5/2 × 1/4
= 5/8
l) 1/8 ÷ 4=
= 1/8 ÷ 4/1
= 8/1 × 1/4
= 8/4
