1 & 11/12

1 = 12/12
1/4 = 3/12
2/3 = 8/12

Total = 23/12 & thus 1 & 11/12

I wish I'd seen this one earlier. I almost feel like a fraud giving the same response as the majority of others who gave a correct answer. It's 1+11/12 (One and eleven twelfths).

If you need to know how to do it, you find a common denominator (the bottom number) that is divisible by both of the denominators given. In your example it is obviously 12ths. Now, with each fraction you divide the given denominator into 12, and then multiply the numerator (the top number) by that number. i.e. in the first fraction 4 goes into 12 three times. Multiply that 3 by the numerator (3 times 1). That gives 3. The first fraction therefore becomes 3/12.

In the second fraction, divide the given denominator (3) into 12. That gives you 4. Multiply the numerator (2) by 4, which gives 8. That fraction then becomes 8/12.

Add the two fractions together 3/12 plus 8/12. That makes 11/12.

Don't forget, however, that you have a whole one, which is equivalent to 12/12 (Twelve twelfths). Add that to the 11/12 that you already have, which gives 23/12. To change it back into a whole number, plus the remainder, divide the numerator (23) by the denominator (12). Obviously, this gives you the end result of 1+11/12.

Sorry I made it so long-winded. I simply wanted to explain how you get to the result for any future fractions that you need to add together. (It's also a similar process if you wish to subtract fractions from each other. You still find a common denominator, and work it out in a similar fashion.)

1 + 1/4 + 2/3

= 12/12 + 3/12 + 8/12

= 23/12

= 1 11/12

stumble on a undemanding denominator, this occasion the backside undemanding denominator is 12. i.e. 2/3 x 4/4 = 8/12 a million/4 x 3/3 = 3/12 you haven't any longer replaced the fraction considering you're merely multiplying by way of a million (4/4 = a million, 3/3 = a million) Then merely upload the numerators: 8/12 + 3/12 = 11/12

1/1+1/4+2/3
=12/12+3/12+8/12
=23/12
=1 and 11/12

To add fractions first you need to have a common denominator.

The usual way of doing this is to multiply their denominators.

so, 3 x 4 x 1 = 12 - thats your common denominator.

Next you convert all the numbers to 12ths

1 = 12/12
1/4 = 3/12
2/3 = 8/12

now you can add all your 12ths: 12 + 3 + 8 = 23

you have 23/12 which is 1 11/12

You dont really need to convert the whole numbers to fractions - you can simply add them after you add the fractions.

Firstly, put all the numbers over the lowest common denominator (this is 12 in this case, as 1, 3 and 4 all go into 12).

12/12, 3/12, 8/12

Then add all the numerators (the top numbers) together and out them all over 12, giving your answer.

(12+3+8)/12=23/12

This can left as a top heavy fraction (23/12) or changed onto a mixed number (1 + 11/12)
