1. [tex]\frac{3}{8} =\frac{x}{30}[/tex] Multiply 30 on both sides
[tex]\frac{3}{8} (30)=\frac{x}{30}(30)[/tex]
[tex]\frac{90}{8} = x[/tex]
[tex]\frac{45}{4} = x[/tex]
2. [tex]\frac{7}{5} =\frac{k}{18}[/tex] Multiply 18 on both sides
[tex]\frac{7}{5}(18)= \frac{k}{18} (18)[/tex]
[tex]\frac{126}{5}=k[/tex]
3. [tex]\frac{4}{6}= \frac{m}{9}[/tex] Multiply 9 on both sides
[tex]\frac{4}{6}(9)= \frac{m}{9}(9)[/tex]
[tex]\frac{36}{6} =m[/tex]
6 = m
4. [tex]\frac{5}{9} = \frac{8}{w}[/tex] Multiply w on both sides
[tex]\frac{5}{9} (w)=\frac{8}{w} (w)[/tex]
[tex]\frac{5}{9}w = 8[/tex] Multiply 9/5 on both sides
[tex](\frac{9}{5} )\frac{5}{9}w=8( \frac{9}{5})[/tex]
[tex]w = \frac{72}{5}[/tex]
