Answer 1

Hey there!

"What ratio forms a proportion with
`(14)/(42)` ?"

-
`(14)/(45) =0.56` (for the decimal)

• 
  `A) (1)/(4)`
  `=0.25`
  `(incorrect)`
• 
  `B) (7)/(21)`
  `=0.33`
  `(Incorrect)`
• 
  `C) (12)/(40)`
  `0.3`
  `(incorrect)`
• 
  `D) (28)/(80)`
  `0.7`
  `(incorrect)`

But in order for you to solve this particular equation you'd have to go in with two (like multiplying by two)

• 
  `1*2= 2` ;
  `4*2 = 8`
  `(incorrect)`
• 
  `7* 2= 14` ;
  `21*2 = 42`
  `(correct)`
• 
  `12 *2 = 24` ;
  `40* 2 = 80`
  `(incorrect)`
• 
  `2 * 28 = 56` ;
  `2* 80 = 160`
  `(incorrect)`

Your result:
`\boxed{Answer: B. (7)/(21) }`

Good luck on your assignment and enjoy your day!
