13) LCM of 20 , 5 is 20
Find equivalent fraction for 2/5 with denominator 20
[tex]\dfrac{2}{5}=\dfrac{2*4}{5*4}=\dfrac{8}{20}[/tex]
Now compare
[tex]\dfrac{7}{20} \ < \dfrac{8}{20}\\\\\dfrac{7}{20} \ < \dfrac{2}{5}[/tex]
14) Convert fraction to decimal

[tex]\dfrac{-1}{7}=-0.14\\\\\dfrac{1}{3}=0.3\\[/tex]
0.5, - 0.14 , -0.2 ; 0.3
Least to greatest:
-0.2 ; - 0.14 ; 0.3 ; 0.5
Answer:
-0.2 ; [tex]\dfrac{-1}{7} \ ; \dfrac{1}{3} \ ; \ 0.5[/tex]
