3 3/4 - 1/2

OpenStudy (pyxieyt):

Want me to guide you though it?

OpenStudy (anonymous):

sure thanks

OpenStudy (pyxieyt):

Okay im going to draw it out for you

OpenStudy (pyxieyt):

So first we should turn 3 3/4 into an improper fraction! Do you know how to do that?

OpenStudy (pyxieyt):

Here is some help

OpenStudy (pyxieyt):

Okay lets go to the next step

OpenStudy (anonymous):

3*4=12 12+3=15 15/4- 2/4( 1/2=2/4)=(now u cross subtract which means just subtract the tops from each other) so 15-2= what the put that over 4

OpenStudy (pyxieyt):

Lets make them have the same denominator! Can you try doing that for me?

OpenStudy (anonymous):

3*4=12 12+3=15 15/4- 2/4( 1/2=2/4)=(now u cross subtract which means just subtract the tops from each other) so 15-2= what the put that over 4

OpenStudy (anonymous):

so what is 15-2 @countsrnc ?

OpenStudy (pyxieyt):

Next we turn 1/2 into 2/4 so we can have a common denominator

OpenStudy (anonymous):

what is 15-2 @countsrnc

OpenStudy (pyxieyt):

Next we do 15/4-2/4=? Remember when they have the same denominator only subtract the numerator

Can you try to talk in chat instead of message?

OpenStudy (pyxieyt):

What did question say exactly?

OpenStudy (pyxieyt):

Okay lets try the question again

OpenStudy (pyxieyt):

Jerry had 3 3/4 quarts of milk in his refrigerator. He used 1/2 of the milk for a recipe. How much milk is left in the refrigerator?

OpenStudy (pyxieyt):

Okay lets try to do this differently

OpenStudy (pyxieyt):

the question is Jerry had 3 3/4 quarts of milk in his refrigerator. He used 1/2 of the milk for a recipe. How much milk is left in the refrigerator

OpenStudy (pyxieyt):

Since you said he has 15/4 what is half of that?

OpenStudy (pyxieyt):

Try to divide it by 2

OpenStudy (pyxieyt):

See you got the answer 1 7/8

OpenStudy (pyxieyt):

Good job!
