Quantity of butter = 2/7 pounds

Quantity of sugar= 2/9 pounds

Now we have to find the difference here.

First finding lcd of 7 and 9 , we have 9*7 =63

lcd is 63

Now converting each fraction into lcd form,

Quantity of butter = 2/7 pounds

$\frac{2}{7} = \frac{2*9}{7*9}$

Quantity of butter = 18/63

Quantity of sugar= 2/9 pounds

$\frac{2}{9} = \frac{2*7}{9*7}$

Quantity of sugar = 14/63

$difference = \frac{18}{63} - \frac{14}{63}$

Difference = 4/63

Answer : 4/63 pounds of more butter was used.
