Answer : The number of yards of ribbon she use is, [tex]\frac{1}{42}[/tex] yards.
Step-by-step explanation :
As we are given that the Betty had [tex]\frac{1}{7}[/tex] yards of ribbon. And she used [tex]\frac{1}{6}[/tex] of it.
Now we have to determine the number of yards of ribbon she use.
Number of yards of ribbon she use = Total yards of ribbon × Used ribbon
Number of yards of ribbon she use = [tex]\frac{1}{7}\times \frac{1}{6}[/tex]
Number of yards of ribbon she use = [tex]\frac{1}{42}[/tex]
Thus, the number of yards of ribbon she use is, [tex]\frac{1}{42}[/tex] yards.
