Answer:
[tex]17\frac{1}{3}[/tex] yards.
Step-by-step explanation:
We have been given that the whole class of 26 students made friendship bracelets. Each bracelet took 2/3 of a yard of yarn to make.
To find total yards of yarn used by the class, we will multiply yards of yarn used to make one bracelet by 26.
[tex]\text{Yards of yarn used by the class}=26\times \frac{2}{3}[/tex]
[tex]\text{Yards of yarn used by the class}=\frac{52}{3}[/tex]
[tex]\text{Yards of yarn used by the class}=17\frac{1}{3}[/tex]
Therefore, [tex]17\frac{1}{3}[/tex] yards of yarn were used in all.
