$[tex]30 ........100\% \\ x.........30\% \\ 100 \times x = 30 \times 30 \\ 100x = 900 \\ x = 900 \div 100 \\ x = 9$[/tex]

b.

$</p><p>50.......100\% \\ x.......20\% \\ 100 \times x = 50 \times 20 \\ 100x = 1000 \\ x = 1000 \div 100 \\ x = 10$[/tex]

c.

$700........100\% \\ x......80 \\ 100x = 56000 \\ x = 560$

d.

$250......100\% \\ x......75\% \\ 100x = 18750 \\ x = 187.5$[/tex]

e.

$100........100\% \\ x........65\% \\ 100x = 6500 \\ x = 65$

f.

$84.......100\% \\ x.......25\% \\ 100x = 2100 \\ x = 21$

g.

$90........100\% \\ x........90\% \\ 100x = 8100 \\ x = 81$

h.

$150....100\% \\ x....85 \\ 100x = 12750 \\ x = 127.5$
