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 ,

• $\dfrac{40}{100} \times x = 20$

• $\dfrac{2}{5} \times x = 20$

• $x = 20 \times \dfrac{5}{2}$

• $x = 50 \: \: min$

the required equation is :

• $\boxed{ \boxed{ \frac{40}{100} \times x = 20}}$
