For this case we have to:

Initial weight = [tex]123 \frac {1} {4} = \frac {4 * 123 + 1} {4} = \frac {493} {4} = 123.25 \ pounds[/tex]

Final weight =[tex]120 \frac {1} {2} = \frac {2 * 120 + 1} {2} = \frac {241} {2} = 120.5 \ pounds[/tex]

We subtract to know how many pounds he lost:

[tex]123.25-120.5 = 2.75[/tex]

So, Kerry lost 2.75 pounds.

ANswer:

Kerry lost [tex]2 \frac {3} {4}[/tex] pounds.

Answer:[tex]2.75\ pounds[/tex] or [tex]2\frac{3}{4}\ pounds[/tex]

Step-by-step explanation:

You can convert the mixed numbers to decimal numbers. Divide the numerator by the denominator of the fraction and add it to the whole number part:

[tex]123\ \frac{1}{4}\ pounds=(123+0.25)\ pounds=123.25\ pounds[/tex]

[tex]120\ \frac{1}{2}\ pounds=(120+0.5)\ pounds=120.5\ pounds[/tex]

To calculate how many pounds Kerry lost, you need to subtract his weigth of a month ago and his actual weigth.

Therefore, you get that he lost:

[tex]pounds\ lost=123.25\ pounds-120.5\ pounds[/tex]

[tex]pounds\ lost=2.75\ pounds[/tex] or [tex]2\frac{3}{4}\ pounds[/tex]
