Hey there!
We use "[tex]\bold{x}[/tex]" as the unknown number until we find out what it is
- [tex]\bold{\frac{15}{20}=\frac{3}{x}}[/tex]
- Firstly, we will cross multiply
- [tex]\bold{15(x)=3(20)}[/tex]
- [tex]\bold{15(x)=15x}[/tex]
- [tex]\bold{2(30)=60}[/tex]
- [tex]\bold{15x=60}[/tex]
- Secondly, we will divide both sides by the number [tex]\bold{15}[/tex]
- [tex]\bold{\frac{15x}{15}=\frac{60}{15}}[/tex]
- [tex]\bold{Cancel:\frac{15x}{15}}[/tex] because it gives us the result of [tex]\bold{1}[/tex]
- [tex]\bold{Keep:\frac{60}{15}}[/tex] because it gives us our answer
- [tex]\boxed{\boxed{\bold{Answer:4}}}[/tex]
Good luck on your assignment and enjoy your day!
