Answer:
9/50
Step-by-step explanation:
0.1 is the equivalent of 1/10
You multiply:
[tex]\frac{3}{7} *\frac{1}{10}[/tex]
= [tex]\frac{3}{70}[/tex]
[tex]\frac{3}{70}[/tex]÷[tex]\frac{5}{21}[/tex] is the equivalent of
[tex]\frac{3}{70}* \frac{21}{5}[/tex]
which equals [tex]\frac{63}{350}[/tex], or [tex]\frac{9}{50}[/tex] simplified (divide both sides by 7)
