Answer:
1/2 cup of apple juice
Step-by-step explanation:
Hi,
<u>1/4 cup of apple juice = 1/2 cup of carrot juice</u>
We're trying to find the number of cups of apple juice when the carrot juice is equal to a whole cup. To do this, we have to get 1/2 to a whole number. Simply multiply 1/2 by 2 to get a whole number. Here's what I mean...
<u>1/4 cup of apple juice = 1/2 cup of carrot juice</u>
<u>1/2 x 2 = 1 (whole number)</u>
<u>So, when we have a whole cup of carrot juice we have...</u>
<u>1/4 x 2 (since we multiplied the 1/2 by 2, we have to do the same to the other side).</u>
<u>1/4 x 2 = 1/2</u>
David will use 1/2 cup of apple juice when he makes a cup of carrot juice.
Hope this helps :)
