Answer:
[tex]\dfrac{5}{8}[/tex] pounds.
Step-by-step explanation:
To find how much butter Robin had after baking, we first need to find how much she initially had.
According to the problem Robin had 7/8 of a pound of butter.
She used 1/4 of a pound of butter to make a cake.
This gives us:
[tex]\dfrac{7}{8}-\dfrac{1}{4})[/tex]
Since we have different denominators, we need to first find the LCD of the fractions.
[tex]\dfrac{7}{8}-\dfrac{1}{4}(\dfrac{2}{2}[/tex]
[tex]\dfrac{7}{8}-\dfrac{2}{8}[/tex]
Now that they have the same denominators, we can then subtract them directly.
[tex]\dfrac{5}{8}[/tex] pounds.
