Step-by-step explanation:

Malise has 1 something (may be a pound, any unit) and she uses 1/8 to make pancakes and 1/3 to make a pie. To see what fraction of blueberries are left we have to substract 1/8 and 1/3 from 1:


1-(1)/(8)-(1)/(3)

We have to find the lower common denominator. Since 8has factors 2, 2, 2 and 3 has itself as a factor (and of course 1 for both) the LCD is the product of these two: 8 x 3 = 24.

Now we have to write it and in the numerator, we have to write each numerator multiplied by the quotient between the LCD and each denominator:


(1\cdot(24)/(1)-1\cdot(24)/(8)-1\cdot(24)/(3))/(24)=(24-3-8)/(24)=(13)/(24)

Answer:

The fraction of blueberries left is 13/24
