Hey there!
"[tex]\bold{\frac{3}{5} }[/tex] of a number is [tex]\bold{21}[/tex] find the number "[tex]\bold{\frac{3}{5} =\frac{3}{5} }[/tex]"[tex]\bold{of = multiplication}[/tex] [tex]\bold{a}[/tex] [tex]\bold{number}[/tex] is a [tex]\bold{unknown}[/tex] so we will label it as [tex]\bold{x}[/tex][tex]\bold{21 = 21}[/tex]So, let's now solve our equation [tex]\bold{\frac{3}{5}(x) 21 }[/tex]Firstly, reverse the fraction, ([tex]\bold{\frac{5}{3} }[/tex]) then, [tex]\bold{multiply}[/tex] it on both of your sides [tex]\bold{\frac{5}{3}\times\frac{3}{5}x}[/tex] [tex]\bold{= \frac{5}{3} \times 21 }[/tex][tex]\bold{Cancel: \frac{5}{3} \times \frac{3}{5}x}[/tex][tex]\bold{Keep: \frac{3}{5}\times21 }[/tex] (Solve this, and you will get your answer)[tex]\bold{Answer: x =35}[/tex]
Good luck on your assignment and enjoy your day! ~
