1/2 + 3/4 A. 2/3 B. 4/6 C. 1 1/4 D. 1 2/4

OpenStudy (misssmartiez):

First, we must make the factors in the denominator correspond.

OpenStudy (misssmartiez):

(LCD for this) 2 x what gets us 4?

OpenStudy (misssmartiez):

@Lowkey.S, would you like to assist?

OpenStudy (lowkey.s):

Sure..

OpenStudy (misssmartiez):

Leaving up on the denominator, what do we do?

OpenStudy (jake124):

8

OpenStudy (misssmartiez):

OpenStudy (lowkey.s):

Yes use LCD so, make sure the denimoter is the same number so wouldnt it be 4? ?/4 ?/4

OpenStudy (lowkey.s):

denominator*

OpenStudy (misssmartiez):

Remember, for our 'finding LCD', we do the smallest value they have in common. 4 can be a common value with 2. How does it associate? As Lowkey.S stated, how do we make 2 to 4? We leave 4 alone.

OpenStudy (jake124):

C

OpenStudy (misssmartiez):

Becareful, that is an improper fraction.

OpenStudy (rjtrain1):

1 and 1/4

OpenStudy (jake124):

thats the answer ?

OpenStudy (misssmartiez):

|dw:1475857314277:dw|

OpenStudy (lowkey.s):

hmm yes do you know how to get it after 5/4 you have to make it to mix fraction so 5/4 =1 1/4 because how we get the 5 by adding the numerator so 5/4 make it to 1 1/4

OpenStudy (lowkey.s):

Yes like what @MissSmartiez said

OpenStudy (lowkey.s):

she said it more clearly

OpenStudy (misssmartiez):

If we do it to the bottom, we do it to the top. 1 x 2 = Now 1/2 is 2/4. 3/4 stays constant. 3 + 2 = 5. 5/4 would be the answer.

OpenStudy (misssmartiez):

How do we make this improper fraction to a mixed fraction? @Lowkey.S, care to elaborate?

OpenStudy (rjtrain1):

I know its 1 and 1/4 just add the top number and if it gos in the tens or mere the tens place gos in the ones place and the rest gos to the top

OpenStudy (jake124):

i dont see were 5/4 is on the answers

OpenStudy (misssmartiez):

Hold on jake, that is the point indeed. We haven't finished conforming our answer. So far, its 5/4.

OpenStudy (rjtrain1):

its as 1 1/4

OpenStudy (jake124):

yes my answer choice was C

OpenStudy (lowkey.s):

Divide the numerator by the denominator. Write down the whole number answer. Then write down any remainder above the denominator. thats how you make Improper Fraction so as she said its 5/4 so, how would you do that?

OpenStudy (misssmartiez):

^

OpenStudy (lowkey.s):

@jake124 please dont give direct answer! Read the Code of Conduct and obivously you should always explain your answer!

OpenStudy (jake124):

what do you mean this is my question and my answer was C

OpenStudy (misssmartiez):

You are correct. Do you understand why exactly though?

OpenStudy (jake124):

yes
