Anita cut 5 /1/3 m of white clothes into three equal pieces to make three costumes to use during drama festivals to bind 1 m of the costume should required 3/7 m of black cloth

a. Write an expression to determine the length of black cloth required to bind one costume
b. Calculate the length of the black cloth that Anita required to bind one costume

a. The expression to determine the length of black cloth required to bind one costume is: (1 m of white cloth) x (3/7 m of black cloth) = 3/7 m of black cloth.

b. To calculate the length of the black cloth that Anita required to bind one costume, we can substitute the given values into the expression:
(1 m of white cloth) x (3/7 m of black cloth) = 1 x 3/7 = 3/7 m of black cloth.
