Answer:

y = $\frac{2}{9}$

Step-by-step explanation:

multiply $\frac{2}{3}$ by $\frac{3}{3}$ to get $\frac{6}{9}$ :

$\frac{6}{9}$ + y - $\frac{1}{9}$ = $\frac{7}{9}$

simplify:

y + $\frac{5}{9}$ = $\frac{7}{9}$

subract $\frac{5}{9}$ from both sides:

y = $\frac{2}{9}$

Debora [2.8K]

Answer:

Darlene bought more fabric

Darlene bought 3.4 yards more

Step-by-step explanation:

Darlene = 7 yards + 20% extra

= 7 yards + (20% of 7 yards)

= 7 + (20% × 7)

= 7 + (0.2 × 7)

= 7 + 1.4

= 8.4 yards

Chris = 4 yards + 25% of 4 yards

= 4 yards + (25% of 4 yards)

= 4 + (25% × 4)

= 4 + (0.25 × 4)

= 4 + 1

= 5 yards

Darlene bought more fabric

How much more?

Darlene - Chris

= 8.4 yards - 5 yards

= 3.4 yards

Darlene bought 3.4 yards more
