Answer:
Step-by-step explanation:
5) 6 : 18 = [tex]\frac{6*1}{6*3} = 1 : 3[/tex]
6) [tex]10 : 12 = \frac{2*5}{2*6} = \frac{5}{6}= 5 : 6[/tex]
7) [tex]12 : 28 =\frac{4*3}{4*7}=\frac{3}{7}= 3:7[/tex]
[tex]8) 18:24 =\frac{6*3}{6*4}=\frac{3}{4} = 3 : 4\\\\\\9)16 : 20 =\frac{4*4}{4*5}=\frac{4}{5}=4:5\\\\\\10) 15:9=\frac{5*3}{3*3}=\frac{5}{3}=5:3\\\\\\11)5:30 =\frac{5*1}{5*6}=\frac{1}{6}=1:6\\\\\\12)14:10=\frac{2*7}{2*5}=\frac{7}{5}=7:5\\\\\\13)6:16=\frac{2*3}{2*8}=\frac{3}{8}=3:8\\\\\\14)20:35=\frac{5*4}{5*7}=\frac{4}{7}=4:7\\\\[/tex]
To reduce to simplest form, find Greatest Common Factor of the two numbers and divide both numbers by the GCF
21 = 3 * 7
9 = 3 * 3
GCF = 3
[tex]\frac{21}{9}=\frac{3*7}{3*3}=\frac{7}{3}=7:3[/tex]
