Fran bought 6 yards of blue tapestry material. She used it to upholster 3 chairs. How much of the material would che need to upholster 7 chairs?

6/3 = 2 yards each
Take it from there.

make a proportion and cross multiply to solve for x
(6yards/3chairs)=(x yards/ 7 chairs)
(6yards x 7 chairs)/(3 chairs)= x
so 14 yards
