Answer 2

Hey there!

"
`\bold{(3)/(5) }` of a number is
`\bold{21}` find the number "
`\bold{(3)/(5) =(3)/(5) }`"
`\bold{of = multiplication}`
`\bold{a}`
`\bold{number}` is a
`\bold{unknown}` so we will label it as
`\bold{x}`
`\bold{21 = 21}`So, let's now solve our equation
`\bold{(3)/(5)(x) 21 }`Firstly, reverse the fraction, (
`\bold{(5)/(3) }`) then,
`\bold{multiply}` it on both of your sides
`\bold{(5)/(3)*(3)/(5)x}`
`\bold{= (5)/(3) * 21  }`
`\bold{Cancel: (5)/(3) * (3)/(5)x}`
`\bold{Keep: (3)/(5)*21 }` (Solve this, and you will get your answer)
`\bold{Answer: x =35}`

Good luck on your assignment and enjoy your day! ~
