a) [tex]\frac{42}{5}=8,4=> x=8<\frac{42}{5}\\[/tex]
b)[tex]\frac{73}{7}=10,42=> x=10<\frac{73}{7}[/tex]
c)[tex]\frac{108}{11}=9,81=> x=9<\frac{108}{11}[/tex]
14
a)[tex]\frac{46}{7}=6,57=> x=7>\frac{46}{7}[/tex]
b)[tex]\frac{87}{7}=12,42=> x=13>\frac{87}{7}[/tex]
c)[tex]\frac{114}{12}=9,5=> x=10>\frac{114}{12}[/tex]
15
[tex]4=\frac{4*7}{7}=\frac{28}{7}\\ 5=\frac{5*7}{7}=\frac{35}{7} \\=>\frac{29}{7} \\=>\frac{30}{7}[/tex]
16
[tex]6<\frac{33}{x}<7\\x=5=>\frac{33}{5}=6,6[/tex]
