Hi I have a question what is 12 3/4 +5 1/3 I tried solving it myself but I couldn’t do it

The first step is to make everything improper fractions:

So 12 3/4 becomes 51/4 and 5 1/3 becomes 16/3

To add 51/4 and 16/3, both denominators need to be the same, so we can multiply by a factor of 1 to get both denominators to equal 12 as shown:

51/4*3/3=153/12

16/3*4/4=64/12

Now you can just add 153/12+64/12 to get 217/12, which in mixed number form is 18 1/12

So 12 3/4 + 5 1/3 is 18 1/12
