Question

Wilson paints 40% of a bookcase in 20 minutes.

How much more time will it take him to finish the bookcase?
1. Write an equation using equal fractions to represent this situation. Use a box to represent the
total time it takes to paint the bookcase.

please provide the equation!

Answer 1

`\large \mathfrak{Solution : }`

let the total time taken to paint the bookcase be x

now ,

• 
  `(40)/(100) * x = 20`

• 
  `(2)/(5) * x = 20`

• 
  `x = 20 * (5)/(2)`

• 
  `x = 50 \: \: min`

the required equation is :

• 
  `\boxed{ \boxed{ (40)/(100) * x = 20}}`
