Can someone help me find the difference of 9 11/12 - 4 2/3? I'm confused with thr denominators

Question

parthkohli · Answer

$$9{11 \over 12} - 4{2 \over 3} \implies {119 \over 12} - {14 \over 3} \implies \cdots $$Does that help?

anonymous · Answer

11/12 - 2/3; So 12 and 3 are not the same. So we need to make them the same. Well 3 goes into 12, so 12 is going to be the common denominator. Leave 11/12 the same

11/12 - [(4/4)(2/3)]
11/12 - [4*2/3*4)
11/12 - 8/12; now subtract
3/12; reduce
1/4 <----------Answer

Find the least common denominator, @chungerforever

parthkohli · Answer

For that... just find the least common multiple of the denominators.

Isn't the LCD 3?

yeah

hero · Answer

(9 - 4) +  (11/12 - 2/3)

Multiply 2/3 by 4/4 to get
(9 - 4) +  (11/12 - 8/12)

Subtract to get:
      5 +  (3/12)

Reduce 3/12 to get
      5 1/4
