Mark had 1/2 cup sugar and borrowed 3/4 cup from Cary to add to his. How many cups did he have now? Answer 4/6 5/4 1/4

OpenStudy (anonymous):

First convert to common denominators. How many "fourths" are in "one half"? Now take those fourths and add them to the number of fourths you borrowed from cary and you'll see your answer in the list you gave.

OpenStudy (anonymous):

is it 1/4? @qweqwe123123123123111

OpenStudy (anonymous):

No. Let's go one step at a time: How many "fourths" are there in "1/2" ? This can be written as: \[\frac{ 1 }{ 2 } = \frac{ x }{ 4 }\] What is the value of "x"?

OpenStudy (anonymous):

x=2

OpenStudy (anonymous):

YES!!!! Now how many "fourths" did you borrow from cary?

OpenStudy (anonymous):

3/4

OpenStudy (anonymous):

Yes, you borrowed "3" fourths. Now add "2" fourths and "3" fourths, and what do you get?

OpenStudy (e.cociuba):

If Mark had 1/2 cup sugar and borrowed 3/4 he now has 5/4 cups.
