Answer:

Chris has approximately [tex]8\frac{5}{12}[/tex] pounds of apples left.

Step-by-step explanation:

We first want to find out how many pounds of flour he used to make both the apple pies and turnovers.

To do this, we must add [tex]2\frac{1}{3} + 4\frac{3}{4}[/tex].

In order to add them, we must get common denominators by multiplying one of the fractions until both of them have the same denominator. For this, we will shoot for 12.

What number do we multiply 3 by to get 12? 4

What number do we multiply 4 by to get 12? 3

If we multiplied the first fraction's denominator by 4, we must do the same for the numerator. This means 1 x 4 = 4.

If we multiplied the second fraction's denominator by 3, we must do the same for the numerator. This means that 3 x 3 = 9.

Now our fractions look like this:  [tex]2\frac{4}{12} + 4\frac{9}{12}[/tex]

Now if we add them, including the whole numbers, we get [tex]6\frac{13}{12} = 7\frac{1}{12}[/tex]

Now we must take the total pounds of apples and subtract it by the pounds he used: [tex]15\frac{1}{2} - 7\frac{1}{12}[/tex]

We need common denominators again, this time, just mess with the first fraction to make your common denominator 12.

What number do we multiply 2 by to get 12? 6

Now we have this:  [tex]15\frac{6}{12} -7\frac{1}{12}[/tex] = [tex]8\frac{5}{12}[/tex]

Therefore, Chris has 8 5/12 pounds of apples left. Hope this helped!
