how do you figure out the mixed number or improper fraction or something..

i know so far the answer is 9/8 but how do you change that so its a regular fraction? PLEASE HELP ME!!

7/8 + 1/4
= 7/ 8 + 2/8
= 9/8

yup, you'll get that 9/8. next step without cramming ur head is to just remember that if you want to change an improper fraction to a proper fraction is by just dividing the 'number which makes it improper' which in this case is 9(well, if the number was 7, it wouldn't be a problem rite?) so, when you divide the 9 over the 8, (mind, dont use a calculator), you will get a 1 1/8.. okay??

actually, i dont think that u can reduce it to a proper fraction...but u can reduce it to mixed number...

since the answer is 9/8...
divide 9 by 8...
so it will be 1..
then there will be a remainder which is 1..
the remainder will be the numerator and the denominator will be 8..
so the answer will be 1 1/8...

8 is the highest denominator
so inorder to get the common denominator
times the 4 by 2
u also need to times the 1 by 2
7/8 + 2/8 = 9/8
divide the 9 from the 8
and u get 1 1/8

When you add fractions you have to make the denominators (numbers on the bottom) match. The denominator of the first fraction is 8, the second's is 4. Can 4 go into 8? Yes, twice. So, multiply the second fraction by 2/2 to get 2/8.

Now you have: 7/8 + 2/8. So just add the numerators (top numbers) to get 9 and leave the denominator as it is, 8. 9/8!

one way isby using your head and knowing that 1/4 is 2/8 or by using the mathmatical formula.You first mutliply across the bottom numbers only so 8x4=32. For the the next step you take 7/8 and 1/4 and multiply diagonally so you end up with 7x4=28 and 8x1=8. Now add them together giving you 36, 28+8=36. The final step put 36 over 32, 36/32 and find a common denominator. so divide each (the 36 and 32) by 4 which gives you 9/8. 36/4=9, 32-4=8 thus making 9/8

then what they said above

First you change the denominators of both the fradctions to the same. normally,you just take the lowest common multiple of them. in this case, its 8.

So here's the working:
7/8 + 2/8 = 9/8
= 1 1/8
the reason 9/8 is changed to the mixed number (1 1/8). 9 is bigger than eight you that makes one whole already. (one whole is 8/8 in this case). So you right 1 and to get 1/8 you just see that after 8 is subtracted from 9 you get one so its 1/8.

so the answer is 1 1/8!

Hope this helps!

Just find out LCM of all denominators

here LCM of 4 and 8 is 8

So make both denominators as 8 to get
7/8 + 1/4
= 7/8 + 2/8
= (7+2) / 8
= 9/8

This is your answer.

Thank you.

one u have the answer as
9/8 to get to mixed numbers you devide the top numerator by the denominator to get the whole number 1 take to the front.
then take the denominator times by the number just found away from the numerator and you get your fraction part
so you get 1 (1/8)

Eg. 23/6

23 divided by 6 ~ 3.83. so take the hole number of 3.

then 23 minus (3*6) = 23-18=5

take the whole number of the 3 to the font then put the other number just found over the denominator
so the answer is 3 (5/6)

~ stands for approximately.

you would not write it with the () but it is the best way online to demonstraite that the whole number is out the front
