Question

Can the sum of two mixed numbers like 7 9/12 + 2 11/12 be equal to 2 ????? please help me i am in 4th grade i do not understand FRACTIONS!!!!!!!!!!

Answer 1

If would help me explain if I break this into two pieces:

First: add the whole numbers 7 + 2 = 9

Second: add the fractions: In this example, because both of the fractions has the same denominator (the bottom number), you can just add the top numbers (numerators) 9 + 11 to get 20/12. Then, you need to simplify 20/12. You do that by figuring out how many times 12 goes into 12 and how much is left over. In this case, 12 goes into 20 one time with 8 left over. So, 20/12 = 1 8/12.

Now you add both of those two pieces together:
9 + 1 8/12 = 10 8/12.
Now you need to take it one step further to simplify the 8/12 part of the answer. 8/12 can be simplified to 2/3 (divide the 8 by 4 to get 2 and divide the 12 by 4 to get 3), so your final answer is:
10 2/3.

Answer 2

`7(9)/(12)+2(11)/(12)=(7+2)+((9)/(12)+(11)/(12))=9+(9+11)/(12)=9+(20)/(12)\\\\=9+(12+8)/(12)=9+(12)/(12)+(8)/(12)=9+1+(8)/(12)=10+(8:4)/(12:4)\\\\=10+(2)/(3)=\boxed{10(2)/(3)}\\eq2`

the mixed number is greater than 1, therefore the sum of two mixed numbers is not be equal 2, it's greater than 2.

if we have 2 mixed numbers greater than 0!
