Question

a) 2,04 : ( -3,12 )

b) \(\left(-1\frac{1}{2}\right)\) : 1,25

c) 4 : \(5\frac{3}{4}\)

d) \(10\frac{3}{7}\) : \(5\frac{3}{14}\)

Answer 1

a) 2,04 : ( -3,12 )=\(\frac{-17}{26}\)

b)\(\left(-1\frac{1}{2}\right):1,25=-2:\frac{5}{4}=-2\cdot\frac{4}{5}=\frac{-6}{5}\)

c)\(4:5\frac{3}{4}=4:\frac{23}{4}=4.\frac{4}{23}=\frac{16}{23}\)

d)\(10\frac{3}{7}:5\frac{3}{14}=\frac{73}{7}:\frac{73}{14}=\frac{73}{7}\cdot\frac{14}{73}=2\)

Answer 2

a) 2,04:(-3,12)=-17/26

b)(-1 1/2):1,25=-1,5:1,25=-1,2

c)4:5 3/4=4:5,75=16/23

d)10 3/7:5 3/14=73/7:73/14=2
