Using a ratio: (5/7) yards/$2.50 = x yards/$1 where x is the unknown yards
Solving for x we fnd, x = (5/7)/2.5 = .286 yards

Jenny spends $2.50 for 5/7 yard of yarn.
If she were to spend only $1.00, how much yarn could she get?
$1.00 is 40% of $2.50. This is from seeing that 1/2.5 = 0.4 or 40%.
Apply this knowledge to the quantity of yarn.
0.4 = 4/10.
5/7 * 4/10 = (5*4) / (7*10) = 4/14 = 2/7 yard.
