Fractions
Raina had 6/7 of a spool of yarn. From that fraction, she used 2/5 for a project.
The fraction of the spool used for the project is obtained by multiplying both fractions:
[tex]\frac{6}{7}\cdot\frac{2}{5}=\frac{12}{35}[/tex]This fraction is in its simplest form. No reduction is possible because 12 and 35 are coprime.
Answer: 12/35
