Question

Malise picked blueberries. She used
`(1)/(8)`of blueberries. to make blueberry pancakes and she used
`(1)/(3)`of the blueberries to make a blueberry pie. She would like to make blueberry jam with the remaining blueberries. What fraction of blueberries. are left to make blueberry jam

Answer 1

Answer: 1 /8 - 1/3

Step-by-step explanation:

8 x 3 = 24

Answer 2

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
