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
[tex] \frac{2}{7} = \frac{2*9}{7*9} [/tex]
Quantity of butter = 18/63
Quantity of sugar= 2/9 pounds
[tex] \frac{2}{9} = \frac{2*7}{9*7} [/tex]
Quantity of sugar = 14/63
[tex] difference = \frac{18}{63} - \frac{14}{63} [/tex]
Difference = 4/63
Answer : 4/63 pounds of more butter was used.
