When you are counting modulo 12.
For example,
on a clock (4 o'clock + 11 hours = 3 o'clock),
or a calendar (April + 11 months = March).
To add mixed numbers and whole numbers, you simply treat the mixed numbers like they are whole numbers (4 3/4) turns to (4), then add the regular whole number, say, 7, and then re-add the fraction. For example, if you were adding 4 3/4 and 7, you would change 4 3/4 to 4, add 7 to get 11, then add the 3/4 back in, to give you 11 3/4.
Its 8 over 11. Because you add the 1 + 3 + 4 = 8 over 11.
U add 3 to make a whole
Let the number be 'n' So 5 times 'n' is 5n To decrease , subtract '4' Hence 5n - 4 The result is '11' Hence 5n - 4 = 11 Add '4' to both sides 5n - 4 + 4 = 11 + 4 5n = 15 Divide both sides by '5' 5n/5 = 15/5 Cancel down /reduce by '5' n = 3 The answer!!!!!

It is 13/4+3/4 = 4
U add 3 to make a whole
-3/4
-11
1 add 4 is 5 and 2 add 3 make 5. 5 add 5 make 10 so 2 x 10 is 20
-7
add 3+3+3+3 divide it by 3 equals 4
