c) 7/5:x=1
d) 1/4:x=3/4
e) 1/4:x=3

AJUTOR!!!!

Answer 1

A) x=4/9:2/3
x=4/9×3/2
x=4/3 ( deoarece se face si simplificare 9 cu 3 si 4 cu 2)
B) x=1:5/7
x=1/1×7/5
x=7/5
C) x=1:7/5
x=1/1×5/7
X=5/7
D) x=3/4:1/4
X=3/4×4/1
X=3/1
E) x=3:1/4
X=3/1×4/1
X=12/1
G) x=2:1/2
X= 2/1×2/1
X= 4/1

Sper ca te.am ajutat!!
