Which expression has a sum of a 11/12? pls help. explain step by step in a way a 13 year old will understand. a. 10/22+2/12
b. 5/4+3/4+3/4
c. 1/12+5/12+5/12
d. 5/6+6/6

c. they are all parts of 12, and when added together they equal 11/12. The formula to solve non proportionate fractions*or with different denominators* is to CROSS multiply and make the denominators equal, then add the numerators and SIMPLIFY.

*Cross multiply to make the denominator equal (you can google how to make fractions equal)

then add the numerators together

then simplify. PLEASE BE CONSIDERATE OF THE FORMULA AND DONT BE INTIMIDATED BY THE LOOK OF THE PROBLEM. They all have the same formula or method of solving. Good Luck!! I hope this helps.
