Answer:
1.
[tex] \frac{3}{6} - \frac{4}{18} = n[/tex]
Find the LCD of 6 and 18
Multiples of 6 and 18
6=6,12,18
18=18
LCD=18
[tex] \frac{9}{18} - \frac{4}{18} = \frac{5}{18} [/tex]
[tex]n = \frac{5}{18} [/tex]
2.
[tex] \frac{2}{3} - \frac{1}{6} = n[/tex]
Find the LCD of 3 and 6
Multiples of 3 and 6
3=3,6
6=6
LCD=6
[tex] \frac{4}{6} - \frac{1}{6 } = \frac{3}{6} [/tex]
[tex]reduce \: \frac{3}{6} to \: its \: \: lowest \: term[/tex]
Find the GCF of 3 and 6
Factors of 3 and 6
3=1,3
6=1,2,3,6
GCF=3
Divide both by 3
[tex] \frac{3}{6} \div \frac{3}{3} = \frac{1}{2} [/tex]
[tex]n = \frac{1}{2} [/tex]
