Four friends shared 1/2 of one carton of orange juice and 1/4 of another carton of apple juice. What fraction of each carton of
Natalka [10]

Answer:

\dfrac{1}{16}

\dfrac{1}{32}

\dfrac{3}{32}

Step-by-step explanation:

So in the first carton of orange juice 4 friends shared the juice.

This can be shown as:

\dfrac{(\dfrac{1}{2})}{4}

\dfrac{(\dfrac{1}{2})}{4}=\dfrac{1}{16}

The 4 friends got 1/16 of the carton each in the first carton of OJ.

Next for the second carton, it can be shown as:

\dfrac{(\dfrac{1}{4})}{4}

\dfrac{(\dfrac{1}{2})}{4}=\dfrac{1}{32}

The 4 friends got 1/32 of the carton each in the first carton of OJ.

Now to see how much they got in total each, we simply add 1/16 to 1/32

Total OJ each = \dfrac{1}{16}+\dfrac{1}{32}

Total OJ each = \dfrac{3}{32}

Each friend got a total of \dfrac{3}{32} each from both cartons of OJ.
