Answer:
[tex]\frac{11}{36}[/tex] yard
Step-by-step explanation:
Length of string Mrs. Ruiz has = [tex]\frac{11}{12}[/tex] yard
Mrs. Ruiz needs to hang 3 banners using the string.
Having known that each banner uses same length of string to be hung we can divide total length of sting into 3 equal parts.
So, we can divide [tex]\frac{11}{12}[/tex] yard by 3 as
⇒ [tex]\frac{11}{12}\div 3[/tex]
Changing the division sing to multiplication by taking reciprocal of divisor.
⇒ [tex]\frac{11}{12}\times \frac{1}{3}[/tex]
We can now multiply numerators and denominators.
⇒ [tex]\frac{11}{36}[/tex] yard
∴ Mrs. Ruiz must used [tex]\frac{11}{36}[/tex] yard of string for each banner.
